Senior Full-Stack AI engineer building AI-native conversational search and meeting intelligence end-to-end.
United StatesWhat I'm looking for
I’m a Senior Full-Stack AI Engineer who builds product-driven, AI-native systems end-to-end—turning RAG pipelines and LLM orchestration into high-performance backend APIs and real-time web interfaces. I’ve scaled conversational AI and collaboration products, focusing on measurable gains in relevance, latency, and user success.
At Perplexity, I led an AI-powered conversational search platform (Copilot-style), improving multi-turn research success by 22% (45% → 55%), answer helpfulness by 18% (28% → 33%), and reducing median latency by 25% (520ms → 390ms) while scaling to 1K+ RPS. At Otter.ai, I drove real-time meeting assistant capabilities, including transcript search and live summary pipelines—reducing search time-to-first-result by 48%, summary generation latency by 40%, and time-to-capture action items by 35% at 15K+ concurrent sessions, and I mentored engineers to accelerate independent delivery.
Experience
Work history, roles, and key accomplishments
Led end-to-end development of an AI-powered conversational search platform, integrating RAG workflows and LLM orchestration to deliver source-grounded answers at 1K+ RPS. Improved multi-turn research success by 22%, answer helpfulness by 18%, reduced median latency by 25%, and decreased time-to-first-token by 35%.
Drove development of Otter’s real-time meeting assistant, enabling live transcription, collaborative editing, semantic search, and automated summaries for 15K+ concurrent sessions. Reduced p95 orchestration API latency by 32%, cut time-to-first-result by 48%, decreased time-to-capture action items by 35%, and improved summary pipeline performance by 40%.
Enhanced Google Cloud Monitoring dashboards by building high-performance UI components and backend aggregation services for real-time metric exploration. Reduced time-to-interactive by ~25% (est.), implemented gRPC + Protobuf aggregation over Cloud Bigtable, and improved automated test coverage by ~50–100 cases (est.).
