I like building software that brings order to complicated data and unclear requirements. At StockInsights AI, I work on systems for AI-driven financial products.

my work

StockInsights AI - Software Development Engineer

Aug 2024 – Present

I build the AI layer of an equity research platform: a RAG pipeline that auto-summarizes 25,000+ SEC and earnings filings a month, a multi-session AI chat system, and the frontend on top of both. Along the way I've migrated our full-text search off MongoDB Atlas, cut our Vercel bill ~80% by tracking down scraper traffic, and shipped the company's first recurring API revenue with Stripe metered billing.
