Alex Cottner

Worked on core Mozilla infrastructure, focusing on backend and DevOps improvements across mozilla/application-services, mozilla/gecko-dev, mozilla/remote-settings, and mozilla/jira-bugzilla-integration. Delivered features such as selective attachment caching and streamlined CI/CD pipelines using JavaScript, Rust, and YAML. Addressed security by updating production root certificates to maintain secure communications, and improved deployment reliability by correcting Docker image tags and simplifying release configurations. Demonstrated strong configuration management by rolling back unstable changes and removing failure-prone tasks to restore integration stability. Emphasized maintainability through expanded test coverage and documentation, contributing to more robust, consistent workflows and reduced operational risk in production environments.
