Rockstar🎓
Top SchoolMark Phelps is a Principal Systems Engineer and founder with 14 years of experience building cloud-native, scalable systems and developer tools. He founded Flipt, an open-source, GitOps-enabled feature management platform born from his time as a Staff Engineer at GitHub and senior roles at Codeship/CloudBees and Bronto, focused on letting teams ship safely without being woken up by production incidents. His background spans backend services, APIs, and front-end UX work—evident in contributions to GitHub’s official CLI (codespace and API features) and ongoing UI improvements to the Flipt project. Based in North Carolina, he combines hands-on engineering with product sensibility to deliver observable, operable systems for large-scale applications. Notably, he has repeatedly driven migrations and re-architectures (from monoliths to microservices and Cassandra to HBase) that improved performance and operational resilience.
