𝗦𝗲𝗻𝗶𝗼𝗿 𝗙𝘂𝗹𝗹 𝗦𝘁𝗮𝗰𝗸 & 𝗔𝗜 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿 building LLM apps, RAG systems and production SaaS with React, Next.js, Python and TypeScript. 🏆 Top Rated · 5+ years · 100+ projects shipped · $100K+ earned on Upwork 🤖 LLM apps, RAG, AI agents, OpenAI · Anthropic Claude · Gemini ⚡ I build with Claude Code, Cursor and Codex daily, so I ship faster and clean up what AI tools get wrong 🔧 Next.js · React · TypeScript · Python · FastAPI · Node.js · PostgreSQL · Supabase · AWS Most people can call an AI API now. The hard part is making it work in production, where the model returns broken JSON, retrieval brings back the wrong chunk, and the whole thing falls over at real user volume. That's the part I do. 𝗪𝗵𝗮𝘁 𝗜 𝗕𝘂𝗶𝗹𝗱 🔹 𝗔𝗜 & 𝗟𝗟𝗠 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 RAG systems, semantic search, AI agents and multi-agent workflows, chatbots and copilots, prompt engineering with structured outputs and tool calls, OpenAI and Anthropic Claude and Gemini integrations, multi-provider setups with fallbacks. 🔹 𝗥𝗲𝘁𝗿𝗶𝗲𝘃𝗮𝗹 & 𝗞𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 Vector databases, embeddings and chunking strategies, pgvector, hybrid search, knowledge graphs and entity extraction, Graph RAG, document processing pipelines, ingestion from Slack, Notion, PDFs and transcripts. 🔹 𝗔𝗜 𝗗𝗮𝘁𝗮 𝗘𝘅𝘁𝗿𝗮𝗰𝘁𝗶𝗼𝗻 Turning messy documents, video and audio into clean structured JSON. Whisper transcription, multimodal GPT-4o and Gemini, OCR, FFmpeg frame extraction, schema validation so the output stays reliable. 🔹 𝗙𝘂𝗹𝗹 𝗦𝘁𝗮𝗰𝗸 𝗦𝗮𝗮𝗦 & 𝗠𝗩𝗣𝘀 Multi-tenant SaaS, role-based access, admin dashboards, customer portals, CRMs and internal tools, Stripe payments, REST APIs, authentication and permissions enforced at the database, not just the UI. 🔹 𝗔𝗜-𝗔𝘀𝘀𝗶𝘀𝘁𝗲𝗱 𝗖𝗼𝗱𝗲 𝗖𝗹𝗲𝗮𝗻𝘂𝗽 I use Claude Code, Cursor, Lovable and Replit every day, so I know where their output breaks. Loose row level security, keys in the frontend, no error handling, the same logic copy pasted in four places. If you built V1 with AI tools and need it production ready, that's a job I take often. 🔹 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 & 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀 Browser automation with Playwright and Puppeteer, background jobs and queues, webhooks, third party APIs, workflow automation, n8n.

Most inherited apps aren't broken, they just need someone to go through them properly, so I don't recommend a rebuild unless the evidence actually supports one. I tell you what something will really take instead of quoting a number to win the job. And I say when something is outside what I've done, because finding that out mid project costs you more than it costs me. I'm also comfortable with sensitive data work, HIPAA aware architecture, PHI data flows, access control and audit logging, and I'll sign an NDA before we start if that's what your project needs.
