Top SchoolJon Levy is a senior software developer based in Copenhagen with over 8 years of focused backend and database experience and a long programming history stretching back to mainframes and game development. Self-taught and versatile, he favors C#, SQL and careful database design while also shipping cross-platform mobile work using Xamarin/UWP and MVVM. He contributes to notable open-source projects like Xamarin.Forms, where he’s fixed UWP UI bugs and added tests, showing attention to polish and platform-specific adaptation. Comfortable building web and mobile apps—especially Twitter-related products—he balances pragmatic engineering with system design instincts honed across consulting, CMS, and enterprise integrations. An understated detail: his career bridges legacy systems (Cobol/Unisys) to modern .NET stacks, giving him uncommon perspective on robustness and maintainability.
