What I'm looking for

I’m looking to build AI-first enterprise search and automation with strong product ownership, permission-aware retrieval, and production reliability—working with teams that value evaluation, observability, and fast iteration.

I’m a Senior Product Engineer and Full Stack Engineer with 7+ years of experience building AI-first SaaS products, real estate software, and workflow automation systems. I focus on shipping end-to-end product features—from idea to production—with dependable customer-facing reliability.

At Glean, I build AI-first enterprise search and workplace automation experiences using React, TypeScript, Node.js, Python, GraphQL, and PostgreSQL. I improve answer quality with RAG, embeddings, metadata filtering, prompt design, evaluation flows, and permission-aware retrieval.

I also develop product experiences for AI assistants, knowledge search, summaries, user feedback, and mobile-friendly productivity workflows. I build permission-aware backend APIs and integration layers that connect enterprise data, user context, access controls, and third-party business tools.

Previously at EliseAI, I built AI-powered real estate automation using React, TypeScript, Node.js, Python, FastAPI, PostgreSQL, Redis, and AWS—including conversational workflows, dashboards for operations, and integrations with CRM and property data. Across roles, I prioritize observability, structured logging, validation/retries, performance, and release stability to keep automation reliable in production.
