About

I’m a Senior .NET Engineer with 20+ years of experience building and stabilizing web applications and distributed systems. Most of my work revolves around untangling complex or aging systems—modernizing legacy code, improving performance, and turning fragile architectures into scalable, maintainable solutions. I’ve worked across the stack with C#, .NET, WebAPI, Blazor, Angular, and SQL Server, along with messaging patterns using Service Bus and RabbitMQ. Lately, I’ve been focusing more on API design, identity (OIDC/OAuth2), and building secure, production-ready systems. I’m currently exploring remote opportunities, including roles involving modernization of secure or regulated platforms. I’m a U.S. citizen and open to positions that require or sponsor a security clearance. If you’re building something interesting or need help stabilizing a complex system, feel free to reach out.
