ABOUT

Building reliable systems at massive scale

I am a Senior Software Engineer with 10 years of experience building large-scale systems at Reddit, Klaviyo, Google, and DataBackfill. I specialize in production conversational AI, LLM orchestration, and distributed data processing.

My work focuses on deep system design and end-to-end delivery. Whether improving latency for 150M+ users or optimizing cost-aware model routing for AI platforms, I enjoy tackling problems that improve performance and user engagement through measurable data.

I am passionate about building production guardrails, evaluation infrastructure, and scalable telemetry. I value cross-functional collaboration with product and data science teams to iterate on AI-driven features that perform reliably under heavy traffic.

Strong background in backend infrastructure, including cloud architecture on GCP and AWS, microservices, and event-driven systems.
