Worked on the denoland/chromium_build repository to streamline the Chromium build system by removing legacy reclient-based remote linking support. Focused on build system configuration and code cleanup using GN, the work aligned the build pipeline with the migration to Siso’s remote linking, reducing technical debt and simplifying future maintenance. The approach involved carefully retiring obsolete features and updating related configurations to ensure continued compatibility with both CI and local builds. All changes were consolidated into a single, traceable commit, demonstrating disciplined change management. This effort preserved build functionality while minimizing disruption, resulting in a more maintainable and stable build environment.
