At T-Mobile, I design and develop full-stack enterprise applications using C# .NET APIs and React front ends, deployed through GitLab CI/CD in AWS. These applications support 13 business units and streamline intake and data access.

I also developed Slack applications adopted across T-Mobile workspaces and automated Microsoft 365 reporting with Microsoft Graph API, saving approximately 40 hours per month.

At Lockheed Martin, I refactored an IBM Rhapsody testing application from Visual Basic into Java. The change reduced execution time from two days to 45 minutes, eliminated crashes, and enabled automated Jenkins builds.

At Fidelity Investments, I developed enterprise Java applications and participated in migrating large PL/SQL systems to Java-based solutions. I also refactored 13 legacy daemon and batch-processing applications in Enterprise Cyber Security.
