Worked on enhancing multi-tenant database isolation in the tursodatabase/libsql repository by implementing namespace-based control for remote database connections. Extended the remote connection builder and the namespace_from_headers logic to recognize and propagate an x-namespace header, enabling per-namespace routing and more granular access control. This approach allowed remote connections to be configured on a per-tenant basis, supporting precise isolation and management of database access. The work was carried out using Rust and focused on backend development, API design, and database management, demonstrating a methodical approach to improving security and flexibility in remote database connection handling for multi-tenant environments.
