Perform data migration planning, extraction, transformation, mapping, and validation across multi-tier application environments.
Support the development of conceptual, logical, and physical architecture artifacts in alignment with enterprise architecture standards.
Troubleshoot, debug, and resolve complex application errors, database bottlenecks, and performance issues in a timely manner.
Manage code repositories, automated build pipelines, and sprint backlogs using Azure DevOps, Team Foundation Server (TFS), and Visual Studio.
