About Me

I'm a full-stack developer with nearly 10 years of .NET/C# expertise, focused on software architecture, cloud computing, and DevOps. I specialize in migrating large-scale applications to modern platforms, designing clean architecture and DDD-based systems, and implementing robust CI/CD pipelines. I'm equally comfortable building backend APIs and frontend UIs — from Blazor WebAssembly to TypeScript-driven component architectures.
