Worked on the neoforged/NeoForge repository to deliver a feature that enables mods to modify recipe JSON data before deserialization, streamlining bulk recipe changes and enhancing mod compatibility. Leveraging event-driven programming and Java, the solution introduced a pre-deserialization hook that allows for efficient, large-scale updates to recipe files, reducing manual intervention and minimizing deserialization errors during batch operations. The implementation focused on improving workflow efficiency for mod developers and supporting scalable mod management within the ecosystem. All changes were consolidated into a single, auditable commit, ensuring traceability and facilitating cross-team review for future development and maintenance efforts.
