Rockstar🎓
Top SchoolNathan Louie is a Senior Staff Software Engineer and tech lead manager based in San Francisco with a decade of experience building large-scale data platforms, batch and streaming ingestion, governance, and vector search infrastructure. At Notion he led vector search efforts to scale capacity 10x while cutting costs to one-tenth, and now oversees the data lake and search stack. His background spans high-throughput consumer products (Instagram Insights at Meta), geospatial mobility and analytics (Replica), and distributed systems work at MongoDB, giving him a rare blend of product-facing feature delivery and deep systems optimization. He pairs pragmatic full‑stack fluency—APIs, BigQuery/Postgres, FastAPI, TypeScript—with operational instincts for cost and runtime efficiency. Outside work he’s applied his data engineering skills in fast-paced volunteer efforts for political campaigns, demonstrating a willingness to tackle mission-driven technical problems on nights and weekends.
