Summary
🤩
Rockstar🎓
Top SchoolPeter Mackay is a versatile lead software engineer with 15+ years of experience building high-performance systems across C/C++, C#, Objective-C/Swift, JavaScript and Java, and a background in assembly-level debugging. Based in Kinghorn, Scotland, he currently leads mobile engineering at FanDuel where he rebuilt and unified divergent iOS/Android architectures using C#, Xamarin and a message-driven design while shipping complex native iOS apps with Apple Watch support. His career spans games, console emulation and tools—contributions to Vita3K and decaf-emu show practical low-level fixes, graphics refactors and platform-specific compatibility improvements. Equally at home in systems design, multithreading, graphics and audio, he pairs test-driven and agile practices with performance profiling and reverse-engineering skills. He’s self-taught in web and graphics tech like Node.js and WebGL when projects demand it, and has a First Class BEng in Software Engineering from the University of Edinburgh. Not obvious from job titles: he frequently bridges high-level app architecture and low-level platform quirks, turning obscure bugs into stable releases.
