Summary
🤩
Rockstar🎓
Top SchoolDouglas Eichelberger is a Staff Software Engineer in Portland with 11 years of experience specializing in developer productivity and Ruby/Rails platform engineering. He has driven productivity initiatives at Stripe, Headspace, and now Gusto, building tools that scale across large codebases (including work supporting one of the largest Ruby repositories at Stripe) and automating developer workflows like OpenAPI client generation. Douglas contributes to notable open-source projects—improving test automation for Homebrew, refining RuboCop and Tapioca internals, and fixing backend issues in Nightscout—demonstrating a strong focus on code quality and tooling. He combines deep language-level expertise (Sorbet, RuboCop, Bundler) with pragmatic infrastructure work, and is as comfortable shipping UI-backed internal tools as he is optimizing static analysis and type-generation pipelines.
