I'm a product-minded software engineer with 15+ years of experience building zero-to-one products and scaling them into production. I pair hands-on technical depth with engineering leadership to ship products, developer platforms, and complex financial systems.

I'm currently the Engineering Lead at Pool, where I built the banking platform from the ground up and an OAuth-secured MCP platform that lets AI agents safely access financial data and move money. Before that, I was a founding engineer at Browserbase and a tech lead at Block, where I architected Square's Web Payments SDK and led Pay Kit for Cash App Pay. I also maintained dotenv for seven years.
