PySide6 & PyQt6 Software Development, UI Design & Launch Engineering services

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

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 work most often developing Python desktop applications using PyQt6 and PySide6 and have helped a number of teams successfully launch Python-based software both internally and to the market. My focus is on ensuring stability, usability and maintainability of software, and supporting teams setting up packaging and release workflows.

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.
