Worked on the TrollsBrigade/CRAVANT-Proto repository, focusing on multiplayer gameplay features using Unity, Photon Networking, and C#. Delivered networked projectile synchronization by replacing standard instantiation with PhotonNetwork.Instantiate, ensuring consistent combat interactions across clients. Addressed area-of-effect damage logic by simplifying target checks and enhancing debug logs, which improved reliability and reduced troubleshooting time. Developed DeathBox inventory synchronization, enabling item persistence and network-wide updates when characters die, with input handling for controlled deployment. These contributions enhanced multiplayer consistency, item retention, and gameplay fidelity, while also streamlining code maintenance and debugging for scalable multiplayer support in a fast-paced development cycle.

Month 2025-08 — Key feature delivery for TrollsBrigade/CRAVANT-Proto: DeathBox Inventory Synchronization on Character Death. Implemented DeathBox instantiation with the dying character's items, persisted the items, and synchronized DeathBox data across the network. Added input handling to trigger DeathBox creation, improving reliability of loot management during death events and multiplayer consistency. This feature reduces item loss risk and enhances gameplay fidelity. No major bugs fixed this month; focus was on feature delivery and ensuring robust network synchronization. Business impact: stronger item retention, improved player experience, and scalable multiplayer support.
