IntelliJ Plugin Development

IntelliJ is the workbench of many software developers. Countless hours are spent within this development environment.
I offer plugin development to help you to integrate your own tools and to increase productivity and efficiency. At I’m publishing articles about IntelliJ plugin development.

IntelliJ Consulting

I know IntelliJ well. I’m personally using it for more than a decade and also know how it works internally.
If you’re looking for support how to use a JetBrains IDE in your company or organisation or to teach your developers how to create plugins, then I’m happy to help you here.


Joachim designed and implemented the IntelliJ plugin for GitHub Copilot from a standing start.

His expertise in IntelliJ-based products was unparalleled. He was highly productive and worked fully independently in a complex and somewhat uncertain domain as our team was still establishing the requirements and many technical details as he worked. He was also very helpful in onboarding permanent staff to the plugin so that we could maintain it in-house in the longer-term.

We wouldn’t hesitate to hire him again any time we are in need of expertise in JetBrains IDEs.

Joachim is a pure joy to work with. His knowledge of IntelliJ–based products coupled with dedication to meet our business requirements meant the functionality we needed was delivered on time, it works as designed, and we are 100% satisfied with the result.

Highly recommended for anyone in need of a custom extension or plugin to one of products by JetBrains.

About Me

My expertise is the development of JetBrains IntelliJ plugins. With more than 10 years of experience I still love to create extensions for this development environment. This helps others to work more quickly and more efficiently.

I work in a wide range of programming languages, technologies, and environments. Besides IntelliJ, I also do a lot of development in Golang, Kotlin, and Java. When necessary I’m happy to work with HTML, CSS, JavaScript, TypeScript, C++, and more.

I live in the south-west of Germany and work remotely.
