Gabriel Bustamante enhanced platform support and release reliability across several Mozilla repositories over four months. In mozilla/bedrock, Gabriel enabled Linux ARM64 build availability for Firefox download pages by updating backend filtering logic and test coverage using Python and YAML. For mozilla/gecko-dev, Gabriel expanded ESR Firefox distribution by adding linux64-aarch64 support in the Bouncer system, coordinating configuration management and release engineering efforts. Addressing CI/CD reliability in mozilla-releng/fxci-config, Gabriel resolved cron permission issues for automated merge workflows. Additionally, Gabriel improved documentation clarity in mozilla/translations, refining Markdown-based Taskcluster docs to streamline onboarding and reduce ambiguity for build environment maintainers.

June 2025: Implemented Bouncer Platform Support for linux64-aarch64 in ESR Firefox, enabling installers and langpacks to be correctly recognized and processed by the Bouncer system. This work completes the linux64-aarch64 distribution path for ESR Firefox and ties to Bug 1944440. Result: expanded ARM64 Linux coverage, reduced release friction, and more reliable platform distributions across ESR cycles.
