About Gydo

I am a .NET developer with experience in developing and maintaining web applications, APIs, and integrations.

In my daily work, I develop software for various clients, working with technologies such as C#, .NET, and React. This has made me accustomed to working in production environments, with a focus on quality, maintainability, and reliable solutions.

In addition to my full-time position, I am available for freelance assignments during evenings and weekends. I primarily focus on smaller, clearly defined tasks where I can deliver value quickly, such as:

Resolving bugs or improving existing functionality
Developing or extending APIs (.NET / REST)
Adding new features to existing applications
Integrating external systems or services
Improving performance or code quality
I work pragmatically and result-oriented: quickly getting to the core of the problem and solving it without unnecessary complexity.

Are you looking for someone who can quickly step in and deliver a .NET-related task well and efficiently? Feel free to send a message.
