Andy Brandt developed end-to-end private messaging deletion features for the dockur/lemmy and dockur/lemmy-ui repositories, focusing on enhancing user privacy and data lifecycle management. He implemented user-controlled deletion of received private messages on the backend, introducing database schema changes and updating the notification system using Rust and TypeScript. On the frontend, Andy refined the user interface in React to support recipient-side message deletion and streamlined content display logic. He ensured robust client-server alignment by adding targeted tests and upgrading tooling for maintainability. This work demonstrated depth in API development, database management, and cross-repository integration, resulting in a cohesive user experience.
