The shared platform that every mod and proxy plugin on the network is built on. Each feature is a separate module: an API, plus implementations for Fabric servers and the Velocity proxy, so features work the same everywhere.

• Storage on MongoDB and MySQL, with per-player data
• Network messaging and sync (observers and auto-broadcast objects) to keep state consistent across servers
• Economy with multiple currencies, a caching layer and batch transactions
• Teleports and server transfers through the proxy, and network-wide locations
• Chat with channels, plus permissions, commands and events shared by Fabric and Velocity
• Text and placeholders, including Cobblemon, economy and player resolvers
• Config, items, inventory GUIs, cooldowns, rewards and procedural generation
• Migrations from the legacy implementations to the new modules without breaking dependent mods

Dungeons built from rooms. Parties fight through them for a graded score and rewards.

• Content is data-driven. Maps, rooms, triggers and functions are scoped to the room, the map or globally.
• Spawn pools are weighted and scale with difficulty. Bosses have hit phases.
• Runs are scored on skill, speed and exploration, with a currency as the reward.
• An in-game wizard edits dungeons through GUI menus.
• Separate modules add bosses, skills and custom items.

A player-run territory game mode spread across a sharded network of servers.

• Player and group data are cached locally and shared between servers.
• Servers talk to each other through a Redis API of events and requests.
• Engine commands run on the Velocity proxy. Gameplay modules run on the Fabric shards.

Custom mobs and bosses for Cobblemon. They're built from templates with their own models, skills and AI.

The main server mod of a large Cobblemon network, made up of about 80 feature modules.

Shared Gradle convention plugins and a published version catalog, so every project builds the same way from one set of dependency versions.

A mobile and web app for ABA therapy. It's outside Minecraft, but it's the same kind of long-term product work.

A Sponge plugin that relays chat between Minecraft and Discord in both directions, using JDA. It links in-game chat channels (Nucleus, UltimateChat) to Discord channels, keeps staff chat separate and posts server start and stop messages. The MBDiscordLink addon links Minecraft accounts to Discord accounts.

A configurable quests plugin first made for the PixelBuilt server: quest lines, tasks, rewards, quests with a cost, block and entity triggers, NPC storytelling and a progression system. A separate expansion adds Pixelmon tasks.

Server plugins I wrote and published for the Sponge ecosystem, including backpacks, towns, command items, offline player queues, claim tweaks for GriefPrevention, Nucleus hover placeholders and XP parties.

Small public mobile apps, including an inventory and logistics manager. My own portfolio site is also built with Flutter.
