PROFILE

Jonwzheng

Worked on the ReactionMechanismGenerator/RMG-database repository, focusing on improving CI/CD reliability, modernizing build pipelines, and enhancing parameter-fitting workflows. Upgraded continuous integration systems using GitHub Actions and Shell scripting to ensure reproducible builds and reduce intermittent failures, including support for Python 3.9 and Julia tooling. Developed and maintained Jupyter Notebooks for chemical kinetics data analysis, refining parameter fitting processes and improving notebook readability and usability. Removed deprecated workflows to reduce maintenance debt and streamline onboarding. Emphasized cross-language compatibility and deterministic testing, enabling faster feedback cycles and higher data quality in scientific computing environments using Python, YAML, and Jupyter Notebook.
