About Me

I'm a senior .NET developer and Azure specialist with over 10 years of experience in enterprise healthcare and insurance applications. I'm passionate about modernizing legacy systems and building resilient cloud-native solutions.

As an AZ-204 certified developer, I specialize in Azure serverless architecture, durable functions, and secure integrations for regulated industries. I excel at navigating complex codebases and implementing pragmatic solutions that balance business needs with technical excellence.

I'm currently available for remote contract opportunities where I can leverage my expertise in:

  • Azure cloud migration and architecture
  • Legacy system modernization
  • Healthcare compliance (HITRUST/HIPAA)
  • Identity and security implementation
  • ASP.NET APIs
  • Blazor
  • In short, all things .NET
