I’m a UK-based software developer specialising in maintaining and modernising legacy .NET applications, particularly VB.NET and WinForms systems that businesses still depend on. Many organisations rely on internal applications written years ago that are difficult to maintain, hard to upgrade, or incompatible with newer versions of Windows and .NET. I help teams safely improve and modernise these systems without risky full rewrites.
