Backend-Focused Full Stack .NET Developer

Backend-focused software engineer with 3+ years of professional experience designing and delivering
scalable, secure, production-grade backend systems using
ASP.NET Core, RESTful APIs, and SQL Server.

Most of my work is delivered through private repositories and
organization-owned projects, including enterprise platforms, internal systems, and client solutions.

I specialize in building systems that run real businesses, not demo or tutorial projects.
