Summary
🤩
Rockstar🎓
Top SchoolBobby Mcdonald is a Senior Software Engineer with a decade of experience focused on backend development, primarily in Ruby with a strong affinity for Elixir. He moved into engineering from service and support roles, which informs his pragmatic approach to developer experience and internal tooling. As the maintainer of OmniAuth since 2019, he shepherded a major 2.0 release, closed long‑standing issues, and removed a longstanding vulnerable default—OmniAuth sees over 100 million downloads and is used by companies like GitLab. He’s contributed to prominent Ruby gems such as Faraday, Sidekiq, Hashie, and omniauth-oauth2 (adding PKCE support), and has a track record of improving CI, build times, and deployment reliability. At companies from CoverMyMeds to NexHealth and TaskRabbit he led migrations, security remediation, and performance tuning that measurably reduced CI/runtime and onboarding time. Colleagues rely on his ability to quickly onboard into unfamiliar codebases, find impactful improvements, and advocate for frictionless local dev and CI/CD workflows.
