MDAnalysis/mdanalysis
Sep 2015 - Sep 2022
MDAnalysis is a Python library to analyze molecular dynamics simulations.
Role in this project:
Back-end Developer & Test Automation Engineer
Back-end Developer & Test Automation EngineerContributions:189 reviews, 348 commits, 228 PRs in 7 years
Contributions summary:Jonathan primarily focused on enhancing the TPR parser, a core component of the MDAnalysis library for analyzing molecular dynamics simulations. Their work involved implementing support for new file formats, including those used in Gromacs 2018 and 2019, as well as improving the parser's ability to read all bonded interactions. They also implemented tests to verify that the parser correctly interprets all the bond types in gromacs. Furthermore, they improved the robustness and maintainability of the TPR parser through refactoring and documentation updates.

Getting Things GNOME! desktop app development
Role in this project:Full-stack Developer
Full-stack DeveloperContributions:7 commits in 1 year 4 months
Contributions summary:Jonathan contributed to the Getting Things GNOME! (GTG) desktop application by enhancing its quick add functionality. They implemented features for due dates, defer dates, and localization for these date-related attributes within the quick add feature. Furthermore, the user added a keyboard shortcut for the edit button and fixed translation strings, indicating contributions spanning both user interface and underlying application logic. These changes suggest a focus on improving the application's usability and internationalization.
