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.

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.

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 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.
