Matt Mundell spent the past year engineering core backend features and stability improvements for the greenbone/gvm-libs and greenbone/gvmd repositories. He focused on modularizing alerting, asset, and SQL management, refactoring large code sections into dedicated modules to improve maintainability and testability. Using C and CMake, Matt implemented robust memory management, expanded unit test coverage, and integrated AddressSanitizer to catch leaks early. His work included hardening authentication flows, standardizing configuration via UUIDs, and enhancing JSON/XML parsing reliability. By emphasizing code readability, documentation, and build hygiene, Matt delivered a more stable, maintainable platform that accelerates development and reduces production risk.

May 2025: Delivered reliability and maintainability improvements across gvm-libs and gvmd with a focus on memory safety, testing, and clearer data flows. Key features delivered include centralized report export filename retrieval and consistent time access in gvmd to ensure reliable report generation, and a refactor of alert handling into reusable components to improve maintainability. Major bugs fixed include robust error handling for OpenVAS daemon stop/delete scans with missing IDs (with added tests) and memory management and leak fixes in start_scan paths, as well as OSP feed error reporting reliability. Additional fixes include VT data parsing under OPENVASD in gvmd and memory-safe management of openvasd paths. These changes boost stability, reduce crash risk, and improve issue resolution speed. Technologies demonstrated include C/C++ memory management, JSON handling, unit testing, and code refactoring for maintainability, with increased use of UUID/config setting patterns.
