## About

I build the backend infrastructure that makes AI\-powered products fast, reliable, and scalable\.

Right now I'm most excited about where AI meets backend engineering — specifically building agentic pipelines and LLM\-integrated APIs using LangChain, FastAPI, and cloud\-native tooling on AWS\. Core stack: Python · FastAPI · Django · Node\.js · PostgreSQL · MySQL · Docker · AWS · LangChain Happy to connect with founders, product teams, and fellow engineers building AI\-powered products\. Open to collaboration, technical consulting, or just a good conversation about what's possible with LLMs and backend architecture\.
