• Experience supporting existing enterprise applications, including production troubleshooting, root-cause analysis, defect remediation, performance optimization, and technical-debt reduction.

• Demonstrated ability to establish and maintain CI/CD pipelines supporting automated builds, code-quality checks, unit and integration testing, packaging, deployment, and release validation.

• Working knowledge of secure software development practices, including code review, vulnerability remediation, secure secrets handling, access controls, dependency management, and change-management controls.
