What do you do at Justworks?

I'm a player-coach Engineering Manager leading a team of 3. I own frontend for all things onboarding, member and company, plus billing. I set technical direction, review the team's code, and still write production code myself.

Are you open to new roles?

No. I'm happily at Justworks and not looking for a new role. I am open to conversations: EM coffee chats, frontend mentorship, conference speaking, and podcast guesting.

What's your technical background?

7+ years building for the web, starting at Stuller in Louisiana before moving north: Leaflink, Cyclei (founding frontend engineer), and Justworks, where I grew from Software Engineer to Senior to Engineering Manager. As a senior I built the org-wide typed fetch library and shared frontend config libraries, and helped move customer traffic from roughly half to roughly three-quarters onto the new app. Core stack is Vue, TypeScript, and Ruby on Rails, with Go, Node.js, Vitest, Playwright, and GitHub Actions in regular rotation. Very comfortable with AI tooling: Cursor and Claude Code are daily drivers, and I rolled out Claude PR review across our frontend org.

I live in New Jersey and work out of New York City (Eastern Time), hybrid.
