Senior Python Developer specializing 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.

What I can do

I work most often developing Python desktop application development, using PyQt6 and PySide6. I'm the creator of the popular Python GUIs website, which covers these and other Python GUI frameworks.

The majority of my clients from scientific and engineering backgrounds, and are looking to polish prototypes and bring them to market. I 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.

Philosophy

When working with teams my goal is always to leave you stronger and able to continue working without me. In practice that means, building clearer and cleaner systems, system and application architectures, and reproductible patterns. For user-facing software, I can also help to create documentation and learning materials to speed up onboarding.
