Summary
🤩
Rockstar🎓
Top SchoolMichael Samper is a full-stack software engineer with 10 years of experience building scalable, user-focused web applications from internships to production at Twitter and GrowthBook (YC W22). He designed and migrated critical experimentation systems—shifting a Scala REST API to Node.js/GraphQL—to dramatically cut build times and accelerate developer velocity while centralizing experiment metadata and workflows. At Twitter he led cross-functional projects that replaced scattered tracking spreadsheets with a reusable experiment wizard and mentored interns to apply BigQuery and Elasticsearch at scale. He contributes back-end improvements to the open-source GrowthBook A/B testing platform, adding BigQuery integration and CDN/cache workflows. Based in San Francisco, he pairs technical craft with mentorship and DEI advocacy, and—less obviously—brings the same attention to detail to culinary pursuits and community coffee chats.
