What I'm looking for

I’m looking to leverage my full-stack .NET/Azure and React/Angular expertise to accelerate digital transformation, improve user outcomes, and drive performance-focused, test-driven delivery in a forward-thinking organization.

I’m a Senior .NET Full Stack Engineer focused on delivering cloud-enabled enterprise web applications—especially HIPAA-compliant healthcare platforms. I lead the design and implementation of scalable backend services on .NET Core/Azure and build responsive front-ends with React and Angular, improving performance and reliability through real-world delivery work.

In my recent role, I engineered Azure-hosted microservices from a monolithic healthcare platform, cutting deployment time by 30%, and built a React patient portal with real-time SignalR communication. I also strengthen engineering rigor with xUnit/Moq testing, enhance CI/CD in Azure DevOps, resolve peak-usage bottlenecks with Azure Functions telemetry, and guide architecture discussions while mentoring junior teammates.
