Freelance .NET Developer
for Desktop & Web
Custom software development with .NET (C# & VB.NET, WPF & WinForms) and PHP (Slim & Symfony) — for over 15 years. Solid architecture, clean code, delivered on time.
Does This Sound Familiar?
Aging Legacy Application
Your WinForms or WPF app is becoming unmaintainable. Every change feels like a risk.
Growing Technical Debt
The codebase keeps growing, but the architecture can’t keep up. Refactoring gets expensive — or never happens at all.
Missing .NET Expertise on the Team
Your team lacks the right specialist — and the next deadline is closing in.
New Project, No Clear Architecture
You need a developer who thinks ahead — not just someone who closes tickets.
This is exactly where I come in.
What I Do
From a single feature to a complete project — I build software that works in the real world.
Desktop Development
C#, VB.NET, WPF, WinForms — new applications or modernizing existing software. MVVM, Clean Code, SOLID.
Web Development
PHP, Symfony, JavaScript, VueJS — from backend to frontend. Scalable, maintainable, to the point.
Refactoring & Modernization
Clean up legacy code. Improve performance. Introduce architecture — without rewriting everything from scratch.
Freelance Team Augmentation
Embedded into existing development teams as an external .NET specialist. Remote, self-directed, flexible.
