Senior🎓
Top SchoolJames Abercrombie is a Senior Software Engineer with 11 years of experience building developer tools and front-end systems that help teams move faster. He specializes in React, TypeScript, Node.js and performance profiling, with a proven record of halving page load times and accelerating CI to support daily deploys. At ProductPlan he led migrations to TypeScript, improved test and build stability, and created visibility tooling that connected CI events to Slack for better team feedback. He values developer experience—shipping faster local linting, 3x faster tests, and an internal Storybook—and pairs hands-on implementation with mentoring and process improvements. Now based in Los Osos, CA and currently at Labelbox, he balances a practical engineering focus with an eye for tooling that scales team velocity. Outside of work he’s known for a relaxed personal style (self-described avid sandal-wearer), reflecting an easygoing approach to collaboration.
