About this gig

Is your business running on an old C++ desktop app that nobody wants to touch? I modernize legacy Windows software safely, without a risky full rewrite.


I've spent 9+ years on large enterprise desktop applications and work with MFC, ATL, COM,

Win32 and WPF.


Legacy C++:

  • Upgrade to the latest Visual Studio toolset and C++17/20
  • Fix build errors after upgrades
  • Refactor risky code into testable layers and add unit tests
  • Fix crashes, deadlocks and memory leaks
  • Expose C++ to C#/.NET (C++/CLI, COM interop)


New C# desktop apps:

  • WPF (MVVM) or WinForms
  • File import/export (CSV, Excel, JSON, XML)
  • PostgreSQL / SQL databases
  • Clean, documented source code


Every project starts with an assessment, so you know the plan and the risks before any code changes.

I'm a C++ Application Architect with 9+ years of experience building and fixing large Windows desktop software for enterprise companies. I specialize in hard bugs (crashes, deadlocks, memory leaks), modernizing legacy C++/MFC code, and C#/WPF applications. I also set up AI coding workflows with Claude Code and MCP, and teach C++ to learners and course creators. B.E. Computer Engineering (NUST). I reply fast, explain what I changed, and deliver tested code.
