Rockstar🎓
Top SchoolMarin Usalj is a founder and seasoned software engineer with 11 years of experience building mobile platforms, CI tooling, and security-focused client systems from startups to enterprises. He led mobile and ops efforts at Lyft, drove weekly App Store deployments at Yammer/Microsoft, and built fault-tolerant continuous delivery for iOS and Android. An active open-source maintainer, his projects—such as xcpretty and Alcatraz—are widely adopted across companies like Facebook, Slack, PayPal and have become de facto tools in Xcode and CI workflows. Based in Boulder, Marin blends hands-on engineering, QA/automation expertise, and release engineering practices to reduce friction in developer workflows. He’s equally comfortable founding stealth ventures as he is hardening client-side security and shipping reliable cross-platform delivery systems.
