Ryan Feigenbaum is a Developer Advocate with seven years of experience helping teams adopt and succeed with developer tools, currently focused on GrowthBook. Based in Cincinnati, he blends technical writing and developer relations to make feature flagging and A/B testing approachable for engineering and product teams. His open-source contributions to GrowthBook include glossaries, pre-launch checklists, integration guides (Vercel, Deno Hono, Strapi, Contentful) and experiment templates that improve onboarding and runbooks. That mix of documentation and advocacy shows he prioritizes practical developer experience—turning complex platform features into clear, actionable workflows. He’s equally comfortable translating product needs into integration guides as he is evangelizing observability and experimentation best practices. Colleagues rely on him to bridge product, engineering, and community with concise, usable guidance.
