I build and ship AI-powered web applications from idea to production.
My work includes AI agents, LLM integrations, RAG, tool-calling, real-time systems, and full-stack development with Next.js, React, TypeScript, Node.js, and PostgreSQL.
I've built and deployed three live AI products, including a multi-model AI SaaS platform, a real-time voice AI app, and an agent-based expense tracker.
I focus on building practical, production-ready systems — not just demos — and handle projects end-to-end, from architecture to deployment and debugging.
Live examples available on request.
