About this gig

Looking for a developer who can actually SHIP an AI product not just wire up a ChatGPT API call?


I'm a full-stack AI engineer specializing in building production-ready AI SaaS applications, AI agents, and intelligent web platforms from scratch.


WHAT I BUILD:

  • AI SaaS platforms (multi-tenant, with auth, billing, and role-based access)
  • AI agents & agentic workflows (LangChain, LangGraph, multi-agent systems)
  • RAG chatbots (retrieval-augmented generation with your own documents/data)
  • GPT-4o / OpenAI API integrations into existing websites or apps
  • Full-stack web apps (React/Vite frontend + FastAPI backend + Supabase/Postgres)
  • Stripe payment integration & subscription billing
  • Custom business automation tools (inventory, CRM, finance dashboards with AI features)


My Stack

  • Frontend: React, Vite, Tailwind
  • Backend: FastAPI, Python, Node.js
  • Database: Supabase, PostgreSQL (with Row-Level Security for multi-tenant apps)
  • AI: OpenAI GPT-4o, LangChain, LangGraph, ChromaDB/vector databases, RAG pipelines
  • Payments: Stripe


WHY WORK WITH ME:

I don't just prototype I build with production concerns in mind: authentication, database security, error handling, and scalable architecture.
