Senior🎓
Top SchoolGreg O'lone is a seasoned DevOps engineer and object-oriented software veteran with over two decades of hands-on experience building tooling, frameworks, and automated build systems. He designed a production-grade automated web hosting and CI/CD system at Xojo that reduced build times from roughly 18 hours to 2.5 hours and scales apps across load-balanced Linux services. Comfortable across languages from JavaScript/TypeScript and Bash to Objective-C and Swift, he has taken ownership of macOS/iOS frameworks, shipping features like cross-platform dark mode and on-device iOS debugging. An entrepreneur-turned-engineer, Greg ran his own software company for nearly a decade and has 15 years of remote-work experience with isolated home networks. He combines deep troubleshooting instincts with a knack for quickly learning new languages and tooling, and is now focused on applying his Objective-C/Swift and DevOps expertise to the next challenge.
