Five-plus years building production-grade backends — Python at the core, with deep work across FastAPI, Django, and the full AWS serverless toolkit. I focus on the unglamorous problems: throughput, fault tolerance, observability, the kind of work that quietly keeps products alive.
More recently I've been pushing hard into GenAI and Agentic AI — designing orchestration pipelines where LLMs are first-class citizens, not bolted-on novelty. Numbers I'm proud of: 50% delivery efficiency, 40% async speedups, 1M+ records/day ETL throughput.
