Fan game of the popular anime tower defense game Arknights. Have characters battle each other with familiar abilities taken and enhanced straight from the base game. Made in Unity with a fully deterministic battle engine, complete game state serialization and deserialization, and full support for rollback netcode. Has a tentative backend written with Java and Netty, offering room-based matchmaking and NAT punchthrough negotiation with a custom networking protocol. Uses GGPO C++ bindings for gameplay netcode as of right now.

Provides communication between different Minecraft servers in network (i.e. Buneecord + multiple Spigot instances) over WebSocket, without relying on plugin channels. Supports annotation-based message listener registration (similar to Bukkit’s @EventHandler annotation), bi-directional responses and conversations, as well as sending from one Spigot instance to another via forwarding through the proxy server. YukiMessenger is currently undergoing rework to support RPC-based messaging, with a custom binary protocol and support for custom data type serializers.

Authentication and identity management platform for my services. Provides authentication service for web services and games I developed.
