Available to hire
I specialize in maintaining and extending existing ASP.NET Web Forms applications for public-sector and other critical business portals, adding new features and improving performance without forcing a full rewrite. I provide safe, incremental evolution of legacy systems, including DevExpress support and SQL Server/data logic enhancements.
With 30+ years of experience across ASP.NET/Web Forms, C#, SQL Server and Microsoft CRM/Dynamics, I troubleshoot issues, optimize performance, and deliver UI and functionality improvements that fit operational needs. I work remotely and prioritize clear communication and reliability.
