I'm a Full Stack .NET Developer specializing in scalable enterprise applications, customer-screening systems, ERP platforms, and modern web solutions. Most of my production work lives in ASP.NET Core, SQL Server, and the React / Next.js ecosystem.
I like to start with the data, understand the problem, and then design clear boundaries. I focus on simple architecture, reliable systems, good performance, and documentation that helps the next developer get started quickly.

// Experience
Three roles. A consistent throughline.
Each step has pushed me deeper into systems work — from ERP modules to AML platforms to enterprise-scale .NET.

Notes on .NET, performance, and shipping software.
