What I'm looking for

I seek backend roles building scalable analytics or LLM-assisted products with strong engineering practices, collaboration, and opportunities to improve reliability and cost.

I am a Python backend engineer with 6+ years building high-throughput ingestion systems, analytics pipelines, and LLM-based assistants for analytics and healthcare. I focus on reliable, cost-efficient backends using cloud services, strong testing, and pragmatic performance optimizations.

I have led backend ownership for report APIs and data-quality tooling (BigQuery, Spanner, Pub/Sub, Elasticsearch), restored test coverage from ~40% to ~80%, and reduced report latency and token costs through targeted filtering and pipeline decomposition. I also delivered an MVP LLM assistant with typed contracts, quality checks, and ~90% token reduction strategies.

I enjoy cross-team collaboration, mentoring and teaching—having taught Python to 400+ students—and delivering production-ready systems with attention to security, observability, and developer ergonomics.
