Worked on the FirebirdSQL/firebird repository, focusing on backend development and system programming using C++ to enhance database reliability and security. Over three months, addressed core areas such as encryption subsystem hardening, plugin management, and diagnostic tooling. Improved crypto plugin handling by introducing explicit reload controls and optimizing thread safety, particularly for Windows environments. Enhanced XDR memory operations by adding safety checks to prevent unsafe allocation and deallocation, reducing crash risk during serialization. Refactored the gstat utility to centralize database attachment, enforce access checks, and improve service status reporting, resulting in safer diagnostics and more robust database management workflows.
