Worked on the dockur/lemmy repository to enhance backend integration by exposing several core types through the Public Types API in the core module. This change was implemented using Rust and focused on making internal types accessible to downstream modules and external components, thereby streamlining future integrations and improving overall modularity. The approach involved careful modification of type visibility within the codebase, ensuring that the new API surface could be easily consumed without compromising internal structure. Over the course of the month, the work centered on backend development, laying a foundation for broader extensibility and facilitating smoother collaboration across different parts of the application.
