Description

Do you have a .NET application that is becoming difficult to maintain or evolve?

I specialize in taking over and modernizing existing .NET business applications.

I get involved when your tools become difficult to maintain, evolve, or secure (WPF, WinForms, VB.NET, ASP.NET MVC, .NET Framework).

My approach is pragmatic: quickly understand your existing setup and propose a clear path, without unnecessary redesign.

Specifically, I help you to:

Audit your application (architecture, technical debt, risks)
Secure an existing foundation before any changes
Take over a project that no one masters anymore
Define a realistic modernization roadmap
Gradually migrate to .NET / ASP.NET Core
Implement APIs and evolve your architecture

I can provide operational support as well as technical framing (lead dev / architect).

Examples of recent contexts:

Takeover and security of a critical ASP.NET MVC application
Migration of a large business application to .NET while maintaining legacy systems
Development of real-time tracking and monitoring tools
Industrial projects with field constraints (scanning, production, traceability)

My goal is simple:to help you make the right technical decisions and avoid risky or poorly sized projects.
