Platform contributor
Summary
Works almost entirely in the GTK/WPE ports — Skia compositor internals, texture atlas and buffer format handling, EGL/AHardwareBuffer import paths for the Android WPE backend, plus recurring layout-test gardening. The pattern is platform porting and graphics-buffer plumbing rather than security work: no security fixes in the window, and the single hardening-classified change is an EGL destroy-image guard ordering fix in WPEBufferAndroid where a RELEASE_ASSERT fired ahead of the EGL_NO_IMAGE check. A promising area to sweep for related bugs: the EGLImage/GBM fallback paths this contributor has been reworking, where missing extension entry points and unavailable AHardwareBuffer imports produce lifetime and null-handle edge cases in graphics buffer teardown.
