ASP.NET Backend & Legacy System Specialist | MVC, Web API, SQL Server, Refactoring
I am a professional full-stack developer specializing in ASP.NET MVC, Web API, C#, and SQL Server, with a strong focus on maintaining, refactoring, and scaling existing applications.
I work primarily with legacy and business-critical systems where stability, performance, and clean architecture matter. Many of my projects involve improving poorly structured codebases, optimizing database queries, fixing production issues, and extending existing functionality without breaking current workflows.
My technical expertise includes:
ASP.NET MVC and ASP.NET Web API
C# and Object-Oriented Design
SQL Server and query optimization
Entity Framework
JavaScript, jQuery, and Knockout.js
REST API design and integration
I follow a structured and cautious development approach - understanding the system first, identifying risks, and implementing changes incrementally. This makes my services well-suited for long-term projects, internal tools, SaaS platforms, and enterprise applications.
If you need a developer who can confidently work with existing codebases, improve performance, and deliver production-ready solutions, I can help.
