What I'm looking for

I seek senior engineering roles building cloud-native, scalable systems (C#/.NET, Azure) with strong DevOps, security, and team-mentoring opportunities.

I am a Senior Full Stack Developer with 12+ years delivering large-scale C#/.NET Core applications and cloud-native solutions across healthcare, aviation, and SaaS domains. I design and lead the full SDLC, from system architecture and API development to cloud deployment and performance optimization.

At Independent Health I built .NET 8 microservices supporting 500K+ members with 99.99% uptime, integrated FHIR APIs for secure patient data exchange, and automated eligibility workflows using Azure Functions and Service Bus. I also partnered with InfoSec and DevOps to implement Key Vault encryption and CI/CD pipelines, achieving a 100% HIPAA compliance audit pass rate.

I have a consistent track record modernizing monoliths into containerized microservices, improving deployment velocity and reducing defects, while mentoring teams and implementing best practices in testing, API versioning, and observability to deliver reliable, performant systems.
