Top SchoolJon Thysell is a Senior Software Engineer with 11+ years at Microsoft, currently building the Minecraft Realms client and previously leading the C++ rewrite and ecosystem work for React Native for Windows. He blends deep systems and UI engineering (C++, C#/WinRT, React Native) with strong data and testing instincts—designing telemetry, CI/CD, and testing infrastructures that turned developer signals into product decisions. Jon has shipped platform APIs like XamlDirect, driven migrations to the New Architecture with Hermes, and contributed visible open-source samples and fixes to microsoft/react-native-windows. A pragmatist who prioritizes customer-focused, data-driven solutions, he also brings a unique tester’s ownership mentality—owning defects to resolution and championing measurable quality. Outside work he’s a self-described retro-games-loving, ukulele-playing nerd and active GitHub collaborator, reflecting a practical curiosity that informs both his engineering and community contributions.
