About this gig

I build complete web applications frontend, backend, database, and AI as one connected product, not disjointed pieces. If you need an app that's actually intelligent, not just good-looking, this is that gig.

I'm a backend and AI systems engineer building production-grade apps with React, Node.js, FastAPI, MongoDB, and Redis, with AI (Gemini/OpenAI) woven into core functionality, not bolted on.

Recent work: an AI analytics platform converting natural-language queries into structured insights and live visualizations, and a distributed ticket-booking system handling 465+ req/sec with zero data loss under load. Same engineering rigor on every project clean architecture, proper error handling, deployable code.

What you get:

  • Full frontend (React) + backend (FastAPI/Node.js) built to spec
  • AI integration: chatbots, natural-language search, content generation, automated data analysis
  • Database design (MongoDB/Redis) matched to real access patterns
  • Clean, documented code no black box
  • Deployment support (Docker, Render, Azure)

Ideal for: startups needing an MVP with real AI functionality, founders wanting a fast working prototype, or anyone burned by a "full-stack dev" who only does frontend.
