Senior Angular Developer with 4+ years of commercial experience in building and supporting production web applications.
I specialize in fixing and improving existing Angular projects: debugging complex issues, upgrading Angular versions, improving performance, refactoring legacy code, and setting up or troubleshooting Angular SSR (Angular Universal). I also work with backend integration, especially ASP.NET Core / .NET APIs.
I provide clean, maintainable solutions with clear communication, structured delivery, and predictable results.
