Over a two-month period, contributed to both front-end and backend projects with a focus on robust data handling and user experience. In the vuetifyjs/vuetify repository, addressed a complex DataTable sorting issue by refining multi-sort removal logic, ensuring predictable and maintainable sorting behavior for users. For mercedes-benz/sechub, developed an automatic JSON object validation framework in Java, introducing interfaces and exceptions to enforce structured validation immediately after deserialization. This work strengthened data integrity and established a reusable validation pipeline. Leveraged skills in Vue.js, TypeScript, and JSON processing to deliver targeted solutions that improved reliability and maintainability across both codebases.
