During August 2025, contributed to the isa-group/bpm2025 repository by delivering a focused UI/UX upgrade for the Message Dialog, refactoring its layout, typography, and presentation of author information, timestamps, and content to improve readability and user experience. Addressed critical overlay layering issues by correcting Z-index values across headers, navigation bars, and modals, ensuring consistent and reliable modal behavior throughout the application. These enhancements, implemented using Astro, Vue.js, and CSS, reduced user friction and improved accessibility, supporting faster decision-making in core workflows. The work demonstrated attention to both visual design and frontend stability, resulting in a more cohesive user interface.
