At Tata Consultancy Services, I work on Citibank systems, including migrating a production .NET application to a new server and configuring an Azure DevOps release pipeline to automate deployments. I also developed operational reports that give business teams direct access to transactional data.

Across projects for C.H. Robinson, HME, and DIRECTV at Globant, I developed and maintained .NET services, REST APIs, and automated tests. My work included backend features for HME's drive-thru application and services that report DIRECTVGO channel health and raise alerts.

I've developed enterprise applications for banking, healthcare, government, and retail clients using the Microsoft stack. My experience spans backend and front-end development, SQL Server and Oracle data layers, reporting, and production monitoring.
