Worked on stabilizing the Data Table component in the porscheinformatik/material-addons repository, focusing on improving front end reliability. Addressed a bug related to duplicate keys in the actionGroup by replacing the previous type-based tracking method with an index-based approach. This technical change reduced the risk of UI rendering glitches, ensuring more consistent behavior for end users interacting with data tables. Utilized Angular and HTML to implement and test the solution, demonstrating attention to detail in front end development. The work concentrated on bug fixing rather than feature development, reflecting a targeted effort to enhance stability and maintainability in the codebase.
