Collaborate with Azure DevOps pipelines for version control, automated builds, testing, and continuous deployment (CI/CD).

Conduct technical design walkthroughs, peer code reviews, and impact assessments to enforce code quality and modern design patterns.

Troubleshoot and resolve complex application, database, and infrastructure issues across development, testing, and production environments.

Support application releases, environment migrations, and platform modernizations.

Ensure application interfaces and components align with enterprise security standards and web accessibility guidelines (AODA/WCAG).

Prepare and maintain comprehensive technical specifications, system architecture documentation, and operational runbooks.
