Worked across the zen-browser/desktop, docs, and updates-server repositories to modernize and streamline CI/CD pipelines, focusing on automation, reliability, and security. Delivered features included automated submodule updates with clearer commit messages, standardized artifact naming for improved traceability across Linux, macOS, and Windows, and upgrades to core CI tooling for enhanced cross-OS consistency. In zen-browser/docs, improved workflow organization and maintainability, while updates-server benefited from security-focused upgrades to GitHub Actions. Leveraged skills in Build Automation, Shell Scripting, and Configuration Management, using Bash and YAML to reduce manual overhead, increase release predictability, and strengthen the foundations for safer, faster deployments.
