Summary
🤩
Rockstar🎓
Top SchoolJustin Searls is a veteran software leader and entrepreneur with 17 years of experience building developer-focused tools and consultancies, currently CEO of Searls LLC and co-founder of Test Double. He combines hands-on engineering—contributions to Ruby tooling like standardrb, legacy code refactoring with suture, and front-end testing support such as jasmine-rails—with strategic leadership roles from CTO to VP of Engineering. Justin has a knack for improving developer experience and CI/test ecosystems, and his open-source work reflects a pragmatic, test-driven approach to large codebases. Based in Orlando, he builds the products he wishes existed while remaining available to help other teams scale and modernize. An unusual thread through his career is a sustained focus on tooling that reduces friction for developers, informed by both deep backend refactors and browser-side testing integrations.
