Rockstar🎓
Top SchoolYen-chia Lin is a Senior Backend Engineer based in Linz with over a decade of hands-on experience designing stable, test-covered libraries and internal tools that boost developer productivity. Originally an iOS specialist, he led iOS engineering at Runtastic for 13 years, introducing Swift, maintaining 120+ internal libraries, and shipping core systems like SSO, syncing, analytics, and Bluetooth integrations for hardware products. He’s skilled in CI/CD orchestration—building a Jenkins Mac build farm and migrating it to Bitrise without downtime—and in evolving dependency tooling from CocoaPods to Tuist for large-scale projects. A pragmatist who treats code as craftsmanship, Yen-chia focuses on clean, efficient, well-documented architectures and mentoring teams on best practices. He brings full-stack mobile tooling expertise (Swift/Objective-C, Ruby, Tuist, Fastlane, Docker) and a knack for automating repetitive work to free engineers for higher-value tasks. Outside of production apps, his career shows a pattern of early adoption and platform-porting—from Windows Phone ports to Apple Watch standalone apps—demonstrating adaptability and systems-level thinking.
