Martin Fitzpatrick
Senior Engineer, creator of PythonGUIs.com and author of Create GUI Applications with Python & Qt
PyQt6/PySide6 Developer for Hire
Practical, senior-level Python consulting for teams building software with PyQt6/PySide6.
I am a Senior Python Engineer specialized in desktop application development with Python & Qt. Based in the Netherlands I'm currently available for both short & long-term projects, working remotely with your team.
I have helped a number of teams successfully launch Python-based software both internally and commercially. My focus is on ensuring stability, usability and maintainability of software, and supporting teams setting up packaging and release workflows. Recently I've also been working with teams to refactor, test and optimize AI-generated applications ready for release.
Before working in software development, I worked in biomedical research and data science (PhD and post-doc). That means if you talk to me about your project, I will probably understand it. I'm comfortable wrangling data to provide useful and accurate visualizations in scientific software.

Launch Window
You have something working: an app that works in your lab or on your machine. It solves a real problem and is ready to be used. It's time to release it.
Now, you need to think about:
- Packaging & distribution, cross-platform macOS, Windows & Linux
- Licensing, code protection/obfuscation
- GPL vs. LGPL and PySide6 vs. PyQt6 questions
- Installer design and testing, validation
- Security management, certificates and passing Virus Scanner checks
- UI polish that makes your users want to use your app
- Functional update mechanism
- Error tracking & diagnosis
That's a lot of new, and honestly quite boring, stuff to deal with.
With Launch Window I provide focused launch help for Python GUI projects. Specifically tailored to your project, market and schedule, I'll get your software released professionally.
