[email protected]🇹🇭 (+66) 90 430 4050issarapong.me
iOS engineer with 9+ years delivering high-impact features and platform improvements across APAC and Europe. I build and scale products in Swift and Objective-C, own work end to end, and design for clarity, testability, and long-term maintainability. Strong in service-oriented architecture, CI/CD, automated testing, and rigorous debugging; I improve developer velocity and production reliability through pragmatic refactors and tooling. A collaborative mentor fluent in English, I partner with engineers, PMs, and designers to align trade-offs and ship quality software across cultures.
