Backend Developer

Building software, automation, and Minecraft experiences that solve real problems.

I enjoy learning new technologies and building things that don't already exist. My focus is backend systems, automation, and Minecraft development, where I enjoy solving challenging problems and creating software that feels polished, scalable, and reliable.

About Me

I like building tools that solve unusual problems: plugins, mods, automation systems, Discord integrations, and backend workflows.

Build useful tools before decorative features.

Keep systems understandable enough to maintain later.

Automate repetitive work and document unusual decisions.

Technology

Skills without progress bars

Skills are grouped by real usage instead of arbitrary percentages. Each technology connects back to projects and engineering contexts.

Java

Primary language for Minecraft plugins, Fabric mods, and JVM server tooling.

JavaScript

Used for backend automation, Discord integrations, and browser tooling.

TypeScript

Adds safety to web tooling, userscripts, and portfolio systems.

Python

Used for scripts, automation, utilities, and quick prototypes.

Node.js

Runtime for APIs, automation, real-time systems, and Discord tools.

Express

Minimal API layer for backend services and dashboard integrations.

Discord.js

Discord automation and command interfaces.

Fabric API

Minecraft mod development with rendering, mixins, and versioned builds.

Paper API

High-performance Minecraft plugin development.

Spigot API

Plugin APIs, events, commands, and configuration.

Bukkit API

Core plugin abstractions and server event handling.

Velocity API

Modern proxy plugin architecture and cross-server systems.

BungeeCord API

Legacy proxy plugin compatibility.

Git

Version control and release workflow.

Linux

Server workflow, terminal tooling, and automation.

Docker

Portable runtime environments and future deployment workflows.

Case studies

Featured Projects

Each project is presented as engineering work: problem, architecture, trade-offs, technologies, and lessons learned.

ActiveBackend Automation

MineBot

Production-grade Minecraft Automation Platform

MineBot integrates authentication, proxy management, automation, real-time communication, and hot-reload capabilities into a modular architecture designed for long-running operation.

GoatHornDetector

Minecraft Plugin for Intelligent Goat Horn Event Automation

GoatHornDetector uses multiple fallback strategies to detect goat horn instruments reliably, then dispatches configured automation through server-safe scheduling.
