Rockstar🎓
Top SchoolDavid Federman is a software engineer with a decade of experience building and optimizing developer tooling and web libraries, currently at Microsoft in Renton, WA. He has contributed to high-profile open-source projects such as MSBuild and BuildXL, focusing on build performance, prediction tooling, and allocation reduction to make large-scale .NET builds more efficient. On the front end he has improved the Microsoft Teams JavaScript library by adding deep-linking, robust initialization/versioning, and test coverage, plus documentation automation from JSON schema. His background spans full-stack web development from an early role at White Glove Technologies to sustained systems work at Microsoft, grounded in a Computer Science degree from UT Austin. David combines attention to low-level performance and practical developer experience improvements, a mix that often surfaces in behind-the-scenes optimizations rather than flashy user-facing features.
