Summary
🤩
Rockstar🎓
Top SchoolMatt Jankowski is an independent consultant and seasoned software leader with 17 years of experience building and scaling web teams and products from the grassroots up. Based in the New York City area, he blends hands-on backend and full-stack Ruby on Rails engineering with high-level consulting on team growth, operations, and agency strategy. As a long-time contributor to prominent open-source projects—including Ruby on Rails, RubyGems.org, and several thoughtbot libraries—he has improved performance, security (eg. rate-limiting for RubyGems.org), and testability across critical tooling. Previously as thoughtbot’s COO he helped scale the company from ~25 to 125+ consultants and expanded its geographic footprint while mentoring engineers and acting as interim CTO for clients. He combines pragmatic engineering (database indices, adapter compatibility, test-suite refactors) with operational insight, making him equally effective shipping code or advising leadership. An under-the-radar strength is his sustained focus on developer experience and test infrastructure, which repeatedly surfaces in his open-source fixes and templates.
