Need AI inside your product but don't have the engineering time? I build full-stack AI apps and add AI features to existing software — end to end, production-ready.
WHAT I BUILD
AI features in your app: chat, summarize, classify, generate, recommend
Full-stack AI web apps (React + Python/Node backend)
LLM + API integrations (OpenAI, Claude, Groq) via REST and webhooks
AI agents that plan and run multi-step tasks with tool calling
Auth, databases (Postgres, MongoDB), and AWS deployment
WHY ME 3+ years as a full-stack and AI engineer. I've shipped an AI talent-scouting platform for 2,000+ users, multi-agent orchestrators, and production APIs with ~99.9% uptime. You get clean architecture, real testing, and a deployable result — not a demo that falls apart.
HOW IT WORKS
Tell me your idea or the feature you need
I scope it, confirm the plan and timeline
I build, test, deploy, and walk you through it
WHAT I NEED FROM YOU TO START
A description of the app/feature and who it's for
Whether it's a new build or adding AI to an existing app (+ repo/stack if existing)
Any APIs/services it must integrate with
