Agustin Palqui developed server-side binary persistence for Catacumbas data in the so1unp/2025-lab-05 repository, focusing on enhancing data durability and reliability. He implemented a system in C that loads Catacumbas state from a binary file at startup and saves changes automatically, ensuring data persists across server restarts. This approach leveraged his skills in data persistence, file I/O, and system programming to reduce manual recovery efforts and improve operational stability. Agustin also updated the build process by modifying the Makefile to remove the client executable, aligning build artifacts with the new server persistence functionality and streamlining deployment.
