Kingdom of Notia — Multiplayer Mobile Game Capstone
Lead Developer / System Architect • 2024–2025
Designed the architecture and implemented nearly all core technical systems in a three-person capstone, including the Unity/C# multiplayer client and server, PHP APIs, MariaDB, authentication, combat, inventory, parties, voice communication, dynamic asset delivery, and payment integration. I also wrote and deployed a basic Solidity transfer contract to an Ethereum testnet, verified the C2C transfer flow, and then discontinued integration after researching applicable banking, AML/CFT, and virtual-asset regulations.
