What I'm looking for

I seek a role building reliable, high-throughput backend and cloud systems, collaborating cross-functionally to deliver scalable products, modernize infrastructure, and drive measurable improvements in uptime and performance.

I am a senior software engineer with 7+ years building scalable distributed systems, cloud infrastructure, and full-stack AI-enabled applications. I have led backend services at Square, managed high-throughput order and OTA device-management systems, and delivered production-grade cloud features that prioritize reliability and performance.

I design and implement microservices architectures, RAG/LLM pipelines, and low-latency retrieval systems using vector databases (Pinecone, FAISS, Supabase Vector), relational and NoSQL stores (PostgreSQL, Redis). I build real-time user experiences and robust telemetry, monitoring, and CI/CD practices to reduce incidents and operational risk.

I collaborate cross-functionally with product, mobile, and infrastructure teams to deliver end-to-end features, modernize legacy systems, and optimize performance—reducing technical debt, improving uptime, and cutting incident response and support load.
