PyQt6/PySide6 Developer for Hire
I have helped a number of teams successfully launch Python-based software both internally and commercially. My focus is on ensuring stability, usability and maintainability of software, and supporting teams setting up packaging and release workflows. Recently I've also been working with teams to refactor, test and optimize AI-generated applications ready for release.
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.
