Are you looking for professional help with your Python GUIs project?
I've been developing software with Python for over 20 years, with a focus on GUI development with Python & Qt (PyQt6/PySide6). Following the success of my PyQt/PySide books I've been providing software development and consulting services to teams building desktop applications with Python.
Have a look below for my current consulting services. Need something else? Get in touch and we can come up with a plan that works for you.

Launch Window
This is for when you have something working: an app that works in your lab or on your machine. It solves a real problem and ready to be used and it's time to release it as a real product either publicly or internally.
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 bespoke launch help for Python GUI projects. Specifically tailored to your project, market and schedule I'll get your software released professionally. Saving you time, and headaches, in the process.
PyQt6/PySide6 Developer for Hire
Bring in experience when it matters most. Practical, senior-level Python consulting for teams building real software without the overhead of hiring.
I am a Senior level Python Developer specialized in Python desktop application development, with Python & Qt. Based in the Netherlands, I'm available for short & long-term projects, worldwide, on fixed and hourly billing.
I work most often developing Python desktop application development, using PyQt6 and PySide6 and have a proven track record of getting software ready & released on schedule.
Before working in software development, I worked in biomedical research and data science (PhD and post-doc). That gives me a solid foundation in scientific working, thinking and development. I'm comfortable wrangling data to provide useful and accurate visualizations, both in applications and other workflows.
