I build production AI systems: LLM agents, retrieval-augmented generation (RAG), real-time voice AI, and AI-powered document processing. Most recently, I led a team of 15+ engineers as Director of Engineering at Eqho AI, building a real-time voice-agent platform for call centers (LangChain/LangGraph, Twilio, Deepgram, ElevenLabs). I've also shipped an LLM-powered tender-analysis platform for construction tech (document ingestion, CAD/BIM support, chat with citations) and the full checkout and billing platform for a dynamic-pricing SaaS. I've been writing code since I was ten and building professionally for 10+ years - including white-label apps running on 50+ major automotive sites (with a tool that appraised and bought 5,000+ vehicles within minutes) and HIPAA-compliant telehealth platforms. Stack: TypeScript/JavaScript (React, Next.js, Vue, Node.js), Python (FastAPI, LangChain/LangGraph), Go, PHP (Laravel), PostgreSQL, AWS/GCP, Supabase. I love solving complex problems with maintainable, scalable code - and I'm happy to own a product end to end, from architecture to deployment.
