Worked on the SystemConsultantGroup/S-top-frontend repository to deliver environment-specific CI/CD pipelines, enabling distinct deployment workflows for QA and production. The approach involved introducing a dedicated CI-qa.yml workflow on the develop branch and renaming the main branch workflow to CI-prod.yml, ensuring clear separation between testing and live releases. Leveraging YAML for configuration and GitHub Actions for automation, the developer established isolated deployment processes that reduced cross-environment risk and improved release governance. The work demonstrated proficiency in CI/CD design, Docker, and Git workflows, resulting in faster QA feedback cycles and safer, more controlled production releases without reported bugs during the period.
