Senior Software Engineer at Microsoft

At Microsoft I worked as a Senior Software Engineer mainly focused on healthcare and finance systems. A lot of my work was about modernizing old .NET apps into cloud-native microservices on Azure. I built APIs with .NET 6/7/8, gRPC, and even GraphQL to connect patient portals, provider systems, and finance apps. I also worked on event-driven pipelines using Azure Service Bus, Event Hubs, and Kafka to process claims in real time, which handled more than 50,000 transactions a day. On the frontend, I delivered apps with Angular and React/Next.js, and also used Blazor to create reusable components for finance dashboards. Security and compliance were big priorities, so I integrated Azure AD B2C, OpenID Connect, and full data encryption for HIPAA and PCI requirements. I also set up CI/CD pipelines with Azure DevOps and GitHub Actions, adding automated testing and security scans. On top of that, I led architecture reviews, mentored junior developers, and worked closely with cross-functional teams across different time zones.

Full-Stack Engineer at ExxonMobil

At ExxonMobil I worked as a Full-Stack Engineer on finance and healthcare benefits platforms. Most of my backend work was building APIs with ASP.NET Core 2.1–3.1, using EF Core and Dapper for data access. I also created background jobs with Quartz.NET and Hangfire for things like benefits calculations and nightly reporting. On the frontend side, I built Angular SPAs with RxJS and NgRx, including role-based dashboards for employees and administrators. I focused a lot on performance too — for example, I optimized SQL Server queries and added Redis caching, which cut API response times by about 40%. I was also responsible for secure data integrations with providers using REST, SFTP, and SOAP, with OAuth2 and JWT for security. For DevOps, I set up deployments in Azure DevOps using ARM templates and PowerShell DSC, and worked closely with finance and compliance teams to make sure everything stayed aligned with HIPAA, PCI, and SOX regulations.
