Reed Garmsen is a software engineering lead with 11 years of experience building high-performance graphics and front-end systems, currently leading the PC development team for Forza Motorsport at Microsoft. He has deep expertise in rendering and engine work across multiple roles at Microsoft, combined with a strong history of internships at Google and early full‑stack open-source contributions to Mattermost. Reed blends low-level graphics engineering with practical UI/UX improvements—his open-source work on Mattermost shows attention to accessibility and usability in React and JavaScript. He mentors and teaches, having served as a graduate-level instructional assistant in computer graphics and animation, and repeatedly reduces developer friction through automation and tooling. Based in Sammamish, WA, he is comfortable shipping across the stack from engine intern prototypes to shipped AAA PC features. A detail that stands out: he has moved fluidly between game engine intern prototypes, production rendering, and front-end open-source contributions, demonstrating both breadth and deep technical craft.
