Building scalable backend systems

I'm a backend-focused developer specializing in Java, Kotlin, and Go. I build high-performance services, APIs, and distributed systems with a focus on reliability and clean architecture.

I also develop custom Minecraft server software and plugins using Spigot, Paper, and Velocity, working directly with NMS, ProtocolLib, and network internals. Outside backend work, I enjoy building modern interfaces with React, Vue, and TypeScript.
