Top SchoolBrandon Derosier is a Lead Engineer with 13 years of experience building graphics systems, large-scale distributed infrastructure, and SRE tooling across Google, MIT, and Open edX projects. He helped shape Flutter’s Impeller renderer and low-level GPU work—authoring talks and open-source packages like flutter_scene and contributions to the flutter/engine repository—while also shipping platform features for Android XR. Comfortable from C++ graphics primitives to cloud infrastructure and customer-facing product engineering, he bridges low-level performance work with pragmatic ops and reliability practices. Based in California, he has a track record of moving complex rendering and access-control logic between modules to simplify systems and improve test coverage. Colleagues rely on him to print colors to the screen and keep large distributed services running smoothly.
