.NET Backend Developer | C# | ASP.NET Core | SQL Server | PostgreSQL | EF Core

Junior Backend Developer with hands-on experience building desktop applications and RESTful APIs.

I started my programming journey with C++, building strong foundations in programming, OOP, and data structures, then moved to C# and developed desktop applications using Windows Forms and SQL databases.

I later transitioned into backend development with ASP.NET Core, focusing on secure, maintainable APIs, clean architecture, validation, authorization, and reliable database design.

I am also developing modern AI-assisted development skills to improve my software development workflow while maintaining code quality, security, testing, and maintainability.
