Over three months, Tom Campbell enhanced Android automation and build reliability across mozilla/gecko-dev, mozilla/glean, and mozilla/application-services. He modernized test automation infrastructure in gecko-dev by consolidating scripts and updating CI environments to current Android API levels, using Python scripting and YAML for configuration management. In glean, Tom improved Android build consistency by standardizing NDK versioning, reducing CI noise and onboarding friction. Within application-services, he removed deprecated components and stabilized cryptographic test suites, leveraging Rust and Objective-C. Tom’s work demonstrated depth in automation scripting, dependency management, and code cleanup, resulting in more maintainable, secure, and reliable engineering workflows.
