Top SchoolMartin Fitzpatrick is a freelance Python developer and data scientist with 16 years of experience, based in Utrecht, Netherlands, who builds data analysis, machine learning and visualization tools using the scientific Python stack. He blends backend web work (Django/Flask) and desktop UI development (PyQt), and is the author of "Create GUI Applications with Python & Qt," reflecting a strong focus on practical, user-facing tools. His open-source contributions include meaningful bug fixes and enhancements to matplotlib and hands-on full-stack work in the pythonguis examples, demonstrating attention to cross-platform Qt compatibility and memory-leak fixes.

Comfortable leading small teams and consulting, he is available for remote engagements and often combines teaching/tutoring with client projects to accelerate developer adoption. An understated strength is his knack for smoothing integration pain points—file formats, Unicode, Qt APIs—to make analytic tools more robust in production.
