PROFILE
Kris Brown
Worked on ToposInstitute/CatColab, delivering both feature enhancements and reliability improvements across the stack. Developed Petri Net reachability analysis with a subreachability algorithm, integrating it into the frontend using TypeScript and Rust to enable interactive model checking. Improved user experience by ensuring backlink labels display as 'Untitled' when model names are missing, and enhanced error handling in the text-to-model generation workflow so parser errors are surfaced to users. Strengthened AlgJulia interop by refactoring dependency management in Julia, converting optional dependencies to ordinary ones for greater stability. Collaborated closely with peers, emphasizing maintainability, clear commit practices, and robust engineering solutions.

Mar 1, 2026March 2026 focused on stabilizing core capabilities in ToposInstitute/CatColab by delivering a robust error-handling fix for the text-to-model generation workflow. The bug fix ensures that parser errors are surfaced to users instead of producing an invalid model, significantly improving reliability and user trust in the platform. This work reduces downstream failure modes, improves debuggability, and lays groundwork for future resilience enhancements in the model generation pipeline.
