Message

At GDH, I architect cloud-native Azure microservices and use Claude Code for implementation, refactoring, testing, and technical planning, reviewing every generated change before merge. I redesigned the LeadHub platform using Domain-Driven Design and reached 90% automated test coverage.

I’ve built products across healthcare, staffing, public health, aviation, and payments. At Express Employment International, I architected an OpenID Connect and OAuth 2.0 identity server, while my work on WeAreINTEGRIS supported HIPAA-compliant access to patient information.

I’ve also led and mentored developers, including leading a team of seven at Express Employment International. I draw on experience with .NET, Azure, and software architecture to make complex systems maintainable and testable.
