Build, troubleshoot, and improve CI/CD pipelines for automated build, test, security scanning, packaging, and deployment. Collaborate with product owners, UX/design, QA, DevOps, security, and other engineering teams to deliver production-ready capabilities. Monitor and troubleshoot application issues across the full stack, including performance, reliability, and deployment problems.
