## About Me

I'm a Senior Full-Stack Developer and Team Lead with 5+ years shipping production platforms across real estate, e-commerce, construction, and fintech. I work end-to-end in Laravel, React/Next.js, Flutter, and Python (Django, FastAPI), and I've led cross-functional teams of 5 developers delivering 25+ client platforms.

On the AI side, I build retrieval-augmented (RAG) systems with Pinecone, LangChain, and Sentence-Transformers — including a production Q&A system over 10K+ enterprise documents — and integrate LLM toolchains like the OpenAI and Claude APIs and the Model Context Protocol (MCP).

I care about measurable impact: I cut critical Laravel API response times by 88% (3.5s → 400ms), improved team delivery efficiency by 40%, and instituted PR review and coding standards that hit 95%+ on-time delivery. Now I'm targeting AI / Forward-Deployed Engineering roles where deep integration work drives direct product impact.
