I am a senior software engineer with 8+ years building high-impact product features and platform systems at companies including Glean, GitHub, and Atlassian. I own complex, user-facing systems end-to-end—from React/TypeScript product surfaces and public APIs to backend services, search infrastructure, and performance-critical paths.

Recently I led large product initiatives integrating LLM-powered search and in-product agents into enterprise workflows, delivering conversational search and agent runtimes that reduced query resolution time by 30%+ and achieved ~94% task completion for complex workflows. I designed multi-stage prompt pipelines, RAG retrieval and ranking, and LLM orchestration layers that improved relevance and cut p95 response latency to under 2s.

I balance product-driven thinking with robust engineering: shipping secure, scalable features (Autocomplete, Search APIs, Chat APIs), building LLM quality gates into CI, optimizing model routing and costs, and partnering closely with PM and design to translate ambiguous goals into reliable systems that drive adoption and retention.
