Projects
KingdomsCore: Developed a Kubernetes-based multi-server system for optimized data
synchronization and dynamic scaling, hosted on a public cloud for redundancy. It features auto-
registering servers with a proxy, multi-layered caching using MySQL, Redis, and in-memory
solutions, and centralized logging for efficient monitoring and debugging.
ControlPanel: Created a Spring Boot application to simplify Java application hosting by
wrapping the Linux shell. It supports multi-node management, user-selectable Java versions,
automated SFTP server creation, and independent resource monitoring per Java instance, with
integrated Google 2FA for security.
RoyalSecurity: Designed a Java-based Discord integration for enhancing Minecraft server
security by using Discord as a second authentication factor. Integrated with TicketSystem for
seamless Discord-Minecraft account management, enabling authentication, password resets,
and moderation within the server environment.
CommandManager: Developed a helper library for multi-platform command registration,
supporting platforms like Fabric, Forge, Sponge, Paper, and Velocity. The library standardizes
command creation and registration, simplifying the developer experience across various
platforms.
RedisManager: Created a Redis-based inter-server event management library enabling two-way
communication between servers using events. It supports both one-to-one and broadcast
communication modes, wrapping Redis' pub-sub mechanism for flexible and scalable inter-
server event-driven interactions.
