Worked on the lbalmelli/keio repository to deliver two feature streams centered on model-driven design and documentation. Developed a SysML-based card game simulation model, complete with supporting Markdown documentation, image assets, and packaging for deployment. Also managed the Fatema Final Report documentation, handling the creation and deletion of report directories, Word and PDF files, and placeholder images to streamline asset lifecycle management. Focused on repository hygiene by organizing and updating files, which improved maintainability and onboarding. Demonstrated skills in system modeling, technical documentation, and domain-specific language use, with an emphasis on maintainable workflows and deployment readiness throughout the project.
