Work

I’m currently an L6 SWE on the Web Platform team at Square, focused on build tooling, monorepo infrastructure, and TypeScript platform work. Previously, I spent six years on the Square Online team working on UI component libraries, frontend modernization, and developer experience tooling.

Consulting

If you’re stuck on a tough engineering problem, need someone to audit a slow build, or are seeking broader guidance, I’m available to help.

I specialize in frontend tools and frameworks, with a strong focus on improving DX and infrastructure. And I love helping and connecting with people around the world. If you’re interested in working together, feel free to reach out!
