      "description": "6+ years experience | 40+ Full Stack & AI projects | CS Major | Only 5-star reviews ⭐⭐⭐⭐⭐\n\nYour AI demo worked. Production failed. That's the gap I close.\n\nI'm an AI Developer: production LLM systems – AI saas, AI agents, RAG pipelines and MCP servers – in Python and TypeScript, with 6+ years shipping software.\n\n𝗠𝗬 𝗧𝗪𝗢 𝗕𝗘𝗦𝗧 𝗕𝗨𝗜𝗟𝗗𝗦\n\n1. Trust & Growth – Aura Group, Sweden\n\nAn internal AI product used daily by thousands of the firm's consultants. A RAG system that reads financial filings, news, reviews and market data on publicly traded companies and scores them on trustworthiness and expected growth – every answer cited, so a consultant can verify it before acting. That's enterprise AI Developer work as it actually exists: not a demo, a tool people make decisions with.\n\n2. Nesoi – AI-native learning platform (nesoi.ai)\n\nFounding engineer and first AI Developer on the team, zero to production. The platform turns documents, decks and video into interactive lessons with a real-time AI instructor that adapts pace, language and delivery per learner, across 130+ languages. Live adaptive AI is unforgiving – there is no retry queue when a learner is mid-lesson.\n\nOther systems I've shipped as an AI Developer:\n\n– Orchy AI – agent orchestration platform, end to end: create agents, configure tools, memory and guardrails, chain them into multi-agent workflows, trigger from Telegram or on a schedule\n– AI voice agents calling inbound leads in under 60 seconds – qualification, objection handling, booked straight into Google Calendar\n– Speed-to-lead systems: form submission → AI call → WhatsApp → booked appointment, no human in the loop\n– 100K+ documents through OCR + RAG pipelines\n\nWHERE I DELIVER AS AN AI DEVELOPER\n\n𝗔𝗜 𝗔𝗴𝗲𝗻𝘁 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 – LangChain, LangGraph and custom orchestration: tool calling, memory, guardrails, multi-agent handoff, error handling, observability and evals. This is where an AI Developer earns the title – anyone can call an API, few can keep an agent stable.\n\n𝗠𝗖𝗣 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 – custom MCP servers connecting your APIs, databases and internal tools to Claude, Claude Code, ChatGPT and Cursor. Most teams are stuck here, and few AI Developers have actually shipped one.\n\n𝗥𝗔𝗚 / 𝗟𝗟𝗠 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 – pgvector and Postgres retrieval: chunking strategy, hybrid search, reranking, grounded answers with citations. Retrieval that returns the right chunk rather than the nearest one is the line between an AI Developer and a prompt writer.\n\n𝗘𝗻𝘁𝗲𝗿𝗽𝗿𝗶𝘀𝗲 𝗔𝗜 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻 – OpenAI, Claude and open models dropped into products that already have users, without breaking what already works. AI Developer work for teams where downtime has a cost.\n\n𝗣𝘆𝘁𝗵𝗼𝗻 𝗔𝗜 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 – FastAPI, Django, PostgreSQL, Redis, Celery, background workers, RBAC, clean REST APIs. The backend the AI layer sits on, built by the same person.\n\n𝗔𝗜 𝗩𝗼𝗶𝗰𝗲 𝗔𝗴𝗲𝗻𝘁 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 – Vapi, Retell, ElevenLabs, SIP and phone integration, CRM-connected inbound and outbound calling.\n\n𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗔𝗜 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿, 𝗻𝗼 𝗵𝗮𝗻𝗱-𝗼𝗳𝗳𝘀 – React/Next dashboards, admin panels and internal tools, so one owner carries it from agent logic to the screen the user sees.\n\n𝗛𝗢𝗪 𝗜 𝗕𝗨𝗜𝗟𝗗\n\nMost AI projects fail in the same place: the demo works, production doesn't. Retrieval returns the wrong chunk. The agent loops. The model updates and outputs drift. Building for thousands of daily enterprise users teaches you that an AI Developer's real job is month six, not launch day – logging, evals, fallbacks, retries, human review where it matters, and regression tests that prove the system still works after the next model release.\n\nAgents: langchain, langgraph, mcp server, tool calling, function calling, multi-agent systems, agentic workflows, prompt engineering, rag pipeline, retrieval augmented generation, evals, observability.\n\nStack: python, fastapi, django, typescript, nextjs, react, nodejs, postgres, pgvector, redis, docker, aws, gcp, cloudflare, stripe, playwright.\nModels & integrations: openai api, anthropic claude api, claude code, n8n, make, airtable, hubspot, gohighlevel, slack, whatsapp business api, telegram.\n\n𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞\n\n- Free scoping call – you talk to the AI Developer building it, not an account manager\n- Architecture and an honest cost before any code\n- You own the code – your repo, your infrastructure, no lock-in\n- Documented, logged and supported after launch; retainers welcome\n\n🤝 Need an AI Developer who has shipped at enterprise scale? Send a message or an invitation and I'll record you a personalised Loom showing exactly how I'd build your system.\n\nAI Developer, AI integration, Python AI Developer, OpenAI developer, LangChain developer, MCP developer, RAG, vector database, LLM, AI agents, chatbot development, machine learning, API integration",

That last one is live in my current build, a RAG system paired with a deterministic rules engine in FastAPI, because some answers you generate and some you guarantee.\n\nWhat I build:\nRAG systems & AI chatbots involving retrieval-augmented generation over your documents and data, vector databases (Pinecone, pgvector, FAISS), chunking, reranking, citation-backed answers, and \"chat with your documents\" assistants that don't hallucinate.\n\nAI agents & LLM applications including LangChain, LangGraph, CrewAI, multi-agent workflows, tool calling, memory, human-in-the-loop, MCP; custom LLM integrations, prompt engineering, structured extraction, summarization, and document processing; OpenAI, Anthropic Claude, Gemini, Llama\n\nAI & CRM automation involving custom automation in Python (and n8n where it fits) replacing manual workflows; agentic reporting and CRM integration, including a Zoho CRM reporting agent I'm building now\n\nAI voice & conversational agents including Vapi.ai, ElevenLabs, Twilio; appointment booking, support, and lead-capture agents with natural turn-taking\n\nAI-powered SaaS products: full AI features shipped into real products: recruiting platforms, marketplaces, and document-generation apps, with AI in the core workflow\n\nBuilt on Python/FastAPI with PostgreSQL, Docker, and AWS/GCP. the layer these systems actually run on.\n\nDelivered work:\nAI-integrated recruiting platform replaced a manual, spreadsheet-driven candidate process with automated screening and workflows end to end, cutting hiring time from 2 weeks to 3 days. Client-endorsed: \"Accountable for Outcomes.\"\n\nAI document-generation web app eliminated hours of manual drafting by generating structured, ready-to-send documents on demand\n\nAI concierge for a peer-to-peer marketplace, 50+ AI integrations handling user support and routing, running in production since launch\n\nRAG system scaled to 100K+ documents with tuned retrieval, not a demo-sized prototype\nAI voice agents (Vapi.ai, ElevenLabs, Twilio) under 500ms response latency for natural, smooth turn-taking in booking and support calls\n\nLLM-powered storytelling engine for a mobile app, built the core generative feature the product is built around\n\nI design the architecture before writing code, because AI projects fail on architecture, weak retrieval, no evals, integrations that break when a provider ships an API change far more than on syntax. I reply in hours, send working builds instead of status updates, and stay until it's stable.\n\nSend me an INVITE or MESSAGE me with the messy version, a half-built RAG pipeline, a stalled AI project, an AI feature bolted onto an existing web app that never shipped, a previous dev who vanished. Rescue and takeover work is some of what I do best. I'll audit it and tell you within a day whether it's buildable, what it costs, and how long it takes.",

      "description": "Top Rated Plus | 100% Job Success | 14+ years building production software\n\nI take AI products from \"demos well\" to \"runs the business\" — and connect them to the systems your company already depends on.\n\nMost of my clients come to me at one of two moments:\n\n1. You have an AI prototype (built in Lovable, Replit, Cursor, Claude Code or similar) that works in a demo but breaks on real data, real users or real scale. I audit it, fix the architecture, add evaluation and monitoring, and ship it to production.\n\n2. Your data is trapped across tools — Shopify, an ERP, a CRM, accounting, a 3PL — and your team is copying it by hand. I build the integration layer and the AI agents that work on top of it.\n\nWHAT I BUILD\n- AI agents and automations: Claude API, OpenAI API, MCP servers, RAG pipelines, LangChain, n8n, with evals so you know answers are correct\n- Integrations: Shopify (Admin GraphQL/REST, webhooks, custom apps), ERP and inventory systems (Brightpearl, Cin7, 3PL/WMS), CRMs (HubSpot, Salesforce), accounting (QuickBooks, Xero)\n- Production SaaS: Next.js, React, Node.js, Python (FastAPI/Django), PHP/Laravel, PostgreSQL, AWS\n- Fractional technical leadership: architecture reviews, production-readiness audits, tech-stack decisions for founders\n\nRECENT WORK (client names confidential)\n- Shopify to ERP / 3PL order, inventory and pricing sync for multi-store e-commerce brands\n- Real-time GPS telemetry platform for a dispatch operation running 3,200+ trucks\n- Compliance and document-intelligence features for a MedTech quality-management SaaS\n- Fleet breakdown dispatch platform and a multi-tier CRM/dialer SaaS\n\nHOW I WORK\nI start with a short paid audit or discovery milestone: you get a written assessment, a fixed-scope plan and clear milestones before any large commitment. Many of my client relationships have run for 5+ years.\n\nIf you have an AI prototype that needs to become a real product, or systems that need to talk to each other, send me a message with what you're working on.",

      "description": "I help start-ups, SaaS companies, and product teams build production-ready AI SaaS platforms, AI agents, RAG systems, and full-stack applications from architecture to deployment.\n\nIf your AI prototype is becoming difficult to maintain, your RAG system gives unreliable answers, your agents fail on real-world edge cases, or you're tired of coordinating separate frontend, backend, AI, and DevOps developers, I can take ownership of the complete product.\n\nWith 8+ years of software development experience, my focus is not simply getting a feature to \"work.\" I build systems that are secure, maintainable, scalable, observable, and ready for actual customers.\n\nWhat I can help you build:\n\n✔ AI SaaS & AI MVP Development\nProduction-ready SaaS products with authentication, subscriptions, dashboards, multi-tenancy, APIs, databases, admin panels, Stripe billing, and AI functionality.\n\n✔ AI Agents & Agentic Workflows\nAI agents that research, reason, call tools/APIs, process documents, automate workflows, interact with CRMs, and escalate to humans when required.\n\n✔ RAG & Knowledge-Based AI\nReliable RAG pipelines, document intelligence, semantic search, embeddings, vector databases, citations, retrieval optimization, and guardrails designed to reduce hallucinations.\n\n✔ LLM & Generative AI Integration\nOpenAI, Claude, Gemini, LangChain, LangGraph, function calling, structured outputs, prompt engineering, tool use, and custom AI workflows integrated into existing products.\n\n✔ Full-Stack SaaS Development\nReact, Next.js, TypeScript, Node.js, NestJS, Express, Python/FastAPI, PostgreSQL, MongoDB, Supabase, Redis, REST APIs, GraphQL, WebSockets, and background jobs.\n\n✔ Voice AI & Conversational AI\nAI chatbots, customer-support agents, lead qualification systems, Twilio/Vapi integrations, voice workflows, human handoff, CRM integration, and appointment automation.\n\n✔ Existing Product & AI Prototype Rescue\nAlready built something with Lovable, Cursor, Claude Code, Replit, Bolt, or another AI coding tool? I can review the architecture, remove technical debt, fix security/performance issues, and turn the prototype into maintainable production software.\n\nThe problems I usually solve\n\n- A SaaS MVP needs to launch quickly without creating a codebase that must be rewritten six months later.\n\n- An existing web application needs OpenAI, Claude, RAG, AI agents, or automation integrated properly.\n\n- An AI prototype works in demos but becomes unreliable with real data and real users.\n\n- A founder needs one technical owner who understands frontend, backend, databases, APIs, AI, cloud deployment, and product architecture.\n\n- A business wants to automate repetitive operations without depending on fragile workflows.\n\n- A growing application needs better performance, security, monitoring, testing, or scalability.\n\nHow I build\n\nI use AI-assisted engineering tools such as Claude Code, Cursor, Windsurf, and GitHub Copilot to move faster, but speed never replaces engineering discipline.\n\nProjects are built around clean architecture, reusable components, secure authentication, database design, error handling, logging, testing, documented APIs, CI/CD, monitoring, and production deployment.\n\nYou get clear communication, practical technical decisions, regular progress updates, clean repositories, documentation, and a system another experienced developer can understand and extend.\n\nCore Technology Stack\n\nAI & LLMs: OpenAI, Claude, Gemini, LangChain, LangGraph, RAG, Embeddings, Vector Search, AI Agents, Generative AI\n\nFrontend: React, Next.js, TypeScript, JavaScript, Tailwind CSS\n\nBackend: Node.js, NestJS, Express.js, Python, FastAPI, REST API, GraphQL, WebSockets\n\nDatabases: PostgreSQL, MongoDB, Supabase, Redis, pgvector\n\nCloud & DevOps: AWS, Vercel, Docker, GitHub Actions, CI/CD, Sentry\n\nIntegrations: Stripe, Twilio, Vapi, n8n, Webhooks, CRM APIs, third-party APIs\n\nBest fit\n\nI am a strong fit if you are building an AI SaaS product, AI MVP, RAG application, AI agent platform, automation system, or scalable full-stack application, or if you already have a prototype that needs to become production-ready.\n\nSend me your project brief or existing architecture. I will tell you what I would build, what I would avoid, and the fastest sensible path to production.\n\nSKILLS:\n\nFull-Stack Development · AI Development · AI Agent Development · SaaS Development · Retrieval Augmented Generation · Large Language Model · Generative AI · OpenAI API · Claude · Next.js · React · Node.js · TypeScript · Python · FastAPI · API Integration · PostgreSQL · Supabase · Web Services · n8n",

  "hiring_guide": "AI developers build the intelligent systems that help businesses automate decisions, extract insights from data, and create new products powered by machine learning and generative AI. From predictive analytics in healthcare to recommendation engines in e-commerce, these professionals turn raw data into measurable business outcomes across every industry.\nWhat does an AI developer do?\nAn AI developer designs, builds, and deploys systems that learn from data and make predictions or decisions without explicit programming. Their work spans the full life cycle of an AI project — from defining the problem and preparing datasets to training models, evaluating performance, and integrating finished solutions into production environments. These professionals often collaborate with data scientists, back-end developers, and cloud specialists to bring intelligent features to digital products.\nCommon responsibilities for AI developers include:\nBuilding and training machine learning models using frameworks like TensorFlow, PyTorch, and scikit-learn\n\nDesigning natural language processing (NLP) pipelines for chatbots, content generation, and text analysis\n\nDeveloping computer vision systems for image recognition, object detection, and video analysis\n\nCreating data pipelines that clean, transform, and prepare datasets for model training\n\nDeploying trained models to cloud platforms and monitoring their accuracy over time\n\nHow to hire an AI developer on Upwork\nUpwork gives you a structured process for finding, evaluating, and working with AI developers. Follow these four steps to go from a project idea to a working engagement.\nStep 1: Post a job\nStart with a clear AI developer job description that specifies the AI frameworks your project requires (such as TensorFlow, PyTorch, or Hugging Face) and the programming languages involved (Python, R, or Julia). Include details about the dataset size, the type of model you need, and any deployment requirements.\nSpecify whether the project involves NLP, computer vision, predictive modeling, or generative AI\n\nList the cloud platforms your team uses (AWS, Google Cloud, or Azure) so candidates can confirm their experience\n\nDefine milestones, such as data preparation, model training, evaluation, and deployment\n\nMention whether you need ongoing model maintenance or a one-time build\n\nShare your expected budget and timeline\n\nUse the Job Post Generator, powered by Uma™, Upwork's Mindful AI, to speed things up. Describe what you need in a few sentences, and Uma will draft a job post for AI developers. On average, clients receive their first proposal within three hours of posting a job.\nStep 2: Evaluate candidates\nReview each candidate's portfolio for completed AI projects that match your use case. Look for published models, GitHub repositories with clean code, and demonstrated experience with the specific ML frameworks your project requires.\nCheck for hands-on experience with your target frameworks — TensorFlow, PyTorch, scikit-learn, or LangChain\n\nReview any certifications in machine learning, deep learning, or cloud AI services\n\nAsk for sample outputs or case studies that show measurable results (accuracy improvements, latency reductions, or cost savings)\n\nLook at their Job Success Score and client reviews for past AI projects on Upwork\n\nUma can conduct instant video interviews and provide candidate shortlists with side-by-side comparisons, so you can move quickly without losing rigor in your evaluation.\nStep 3: Interview your top choices\nFocus your interviews on technical depth and problem-solving ability. Ask candidates how they'd approach your specific dataset and business problem rather than relying on generic questions. For suggestions, explore the AI developer interview questions page.\nAsk how they'd handle imbalanced datasets, overfitting, or noisy data in your domain\n\nDiscuss their approach to model evaluation — which metrics they'd prioritize and why\n\nReview their experience with model deployment and monitoring in production\n\nTalk through data privacy and security practices, especially if your project involves sensitive information\n\nYou can schedule interviews directly within Upwork Messages, and you'll get an immediate transcript and summary of each conversation.\nStep 4: Agree on scope and begin work\nDefine a contract with clear milestones that map to your AI project's natural phases. This structure keeps both sides aligned on progress and deliverables.\nSet milestones for each phase — data collection, preprocessing, training, testing, and integration\n\nAgree on success metrics (accuracy thresholds, response times, or error rates) before work begins\n\nDefine ownership of source code, prompts, models, datasets, and documentation\n\nClarify responsibilities for deployment, monitoring, and post-launch support\n\nSpecify secure methods for sharing datasets, API keys, and cloud credentials\n\nUse Upwork Messages and the contract workroom for file sharing, milestone tracking, and ongoing communication. Take advantage of identity verification, payment protection, hourly tracking, and project funds to keep the engagement secure.\n\nUpwork is not affiliated with and does not sponsor or endorse any of the tools or services discussed in this article.

  "faq": [
    {
      "question": "Is hiring an AI developer worth it?",
      "answer": "Yes, if you're building AI-powered products or adding intelligent features to existing applications, hiring an AI developer can be a worthwhile investment. AI developers can build custom chatbots, automate business processes, integrate large language models (LLMs), and create AI-driven features such as recommendations, search, and content generation that directly reduce cost or increase revenue. They can also help you choose the right models, optimize performance, and deploy AI solutions that scale with your business.\nOn Upwork, 89% of first-time clients complete a contract (2025), which speaks to the quality of talent available on the platform — and the ROI of investing in the right professional for your AI project."
