What I'm looking for

I'm looking to lead and build scalable cloud-native enterprise applications, modernize legacy systems, and mentor developers within collaborative Agile teams.

At Availity, I build enterprise healthcare applications for provider connectivity, eligibility verification, claims processing, and payment workflows. I modernize legacy systems into cloud-native microservices, design secure REST and GraphQL services, and improve API response times through database optimization.

Across Availity, Alegeus Technologies, Tribridge, and Syniverse Technologies, I've delivered scalable .NET applications for healthcare, financial technology, and enterprise software. I bring hands-on experience with Azure, C#, ASP.NET Core, Angular, React, event-driven systems, CI/CD, and technical mentorship, including reducing deployment time by 35% and report generation time by 30%.
