I design, build and maintain plugins for JetBrains IDEs — and help teams get the most out of IntelliJ.
IntelliJ is the workbench of many software developers. A typical developer spends countless hours within this development environment.
I offer plugin development to increase your productivity and efficiency and can also help you to integrate your own tools into IntelliJ products. I publish articles about IntelliJ plugin development at plugin-dev.com.
I’ve been working with the IntelliJ Platform for more than 15 years and know how it works internally.
If your own developers build plugins, I’m happy to support them with architecture and code reviews, help with tricky platform APIs, and training to get your team up to speed.
Plugin development is shifting to AI coding agents. They write a lot of code quickly, but they need guidance from someone who knows the IntelliJ Platform well and can tell good code from code that only looks plausible.
I believe that AI-assisted development helps most those developers who know what they are doing. After more than 15 years with the IntelliJ Platform, I do.
Besides client projects, I develop my own commercial plugins. Both started long before AI-assisted development, and today AI agents take on part of the work.
My plugins integrate as seamlessly as possible with JetBrains IDEs, so that users feel right at home, and they support the latest platform features such as remote development and Dev Containers.
A plugin for advanced Bash, POSIX and Zsh script development in JetBrains IDEs.
It provides a debugger, a test runner, refactorings, ShellCheck, a formatter, and runs scripts on macOS, Linux, Windows, and remote machines.
A plugin for Swift and Objective-C development in JetBrains IDEs on macOS, Linux and Windows.
It supports Swift Package Manager and Xcode projects and provides an editor, a debugger, and a test runner, even in Android Studio and WSL.
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 has been a godsend for my product.
He’s fully implemented a top-notch IntelliJ plugin for my custom programming language that my customers love to use.

He’s super easy to work with, is insightful, asks great questions, and is hugely knowledgeable about grammars and language tooling.
Joachim is extremely well organized, writes excellent code and is very reliable. His work has always arrived on time and I have nothing but praise for the quality he delivers.
I would recommend him to anyone looking into IntelliJ tooling and would certainly hire him again.
My expertise is the development of JetBrains IntelliJ plugins. With more than 15 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. I live in the south-west of Germany and work remotely.
