Martin Stühmer

Hello there, I’m Martin, software architect and developer from the Cologne/Bonn area. Right from the start of my professional career, I decided in favor of .NET and Microsoft technologies and tools and have always incorporated them into my work. With more than 15 years of experience in the field of software architecture and development with .NET, my focus is particularly on increasing the quality and performance of development teams, the interaction of the software solution with the target environment and the actual application down to the last byte.

In my position as Director Consulting Services @ CGI, I act as enterprise architect and developer for cloud native and .NET solutions. I am also a trainer for cloud and software architecture. In addition to my professional life, I am involved in the open source communities and currently provide them with various NuGet packages with different focuses and functionalities.

A strong willingness to learn and develop is also part of my everyday life. This was taken to a new level for me in 2021 after I successfully completed my IHK trainer and my Microsoft certified trainer this year. In addition, I was able to qualify as a trainer for CGI’s Risk and Cost Driven Architecture program in 2022.

How to Use Copilot Without Becoming Its Puppet

In a previous article, we laid it out – unfiltered: Copilot turns junior devs into syntax secretaries.

Not because it’s evil. But because it removes friction before understanding.

It gives you working code before you know what working even means. It creates the illusion of progress, while slowly eroding the very skills that define a software engineer: reasoning, decision-making, and technical ownership.

Copilot Turns Junior Devs Into Syntax Secretaries

The hype around GitHub Copilot (or any other AI code assistant) is deafening. AI-assisted coding. Effortless automation. 10x productivity.

But here’s the harsh truth: Copilot isn’t empowering junior developers – it’s deskilling them.

Vibe Coding in .NET: Creative Catalyst or Maintenance Risk?

In the world of software development, there’s a recurring tension between discipline and improvisation. Somewhere along that spectrum lies a phenomenon increasingly referred to as Vibe Coding. The term evokes a style of development where engineers follow intuition and momentum rather than formal plans, processes, or design patterns.

It’s fast, fluid, and occasionally brilliant. But is it sustainable in a .NET-based enterprise context?
