Worked on the it-at-m/dave-frontend repository to enhance frontend user experience in data visualization workflows. Focused on improving chart tooltips by refining their appearance and ensuring they remain within chart boundaries, which clarified data presentation and improved usability. Applied consistent background and text formatting across multiple chart components and reordered vehicle categories for more intuitive navigation. Addressed Zeitblock UI issues by implementing conditional rendering and disabling controls when not applicable, reducing the risk of user errors. Utilized JavaScript, TypeScript, and Vue.js with Vuetify to deliver these targeted features and bug fixes, resulting in smoother and more predictable user interactions.
