What I'm looking for

I'm looking to lead and build scalable, secure, high-performance enterprise applications, contributing to architecture, cloud-native development, API design, CI/CD, and collaborative delivery across business and technical teams.

I've led .NET development for GDOT's TPRO project management platform, building secure integrations between IBM FileNet and AWS services for document ingestion, storage, retrieval, and archival. I developed ASP.NET Core 8 REST APIs, event-driven workflows with Lambda and SQS, and an Ocelot API Gateway for routing, authentication, rate limiting, and observability.

Across Med-Metrix, the Department of Labor, SCIO Health Analytics, CVS Minute Clinic, and other enterprise and healthcare engagements, I've delivered applications supporting physician video calls, unemployment benefits, healthcare analytics, payment integrity, and clinical integrations. My work spans C#, .NET Core, Angular, SQL Server, REST APIs, cloud deployments, and secure identity integrations.

I improve reliability and performance by tuning SQL queries and indexes, refactoring legacy monoliths, building reusable components, and implementing CI/CD validation. I've also built Angular clients, Kendo UI dashboards, MongoDB caching, and data-processing pipelines for high-volume systems.

I'm comfortable leading small teams, mentoring developers, reviewing code, estimating work, and partnering with business and infrastructure stakeholders. I bring a practical focus on secure API design, maintainable architecture, and dependable production delivery.
