Game Infrastructure

Trenend.eu

JavaSpring BootSpigotREST APIsMySQLDockerKubernetesInfrastructureDevOps

One of the largest Czech-Slovak economic Minecraft servers with 1M registrations and 50,000 monthly users in 2021. Led backend architecture, custom gameplay systems, and infrastructure scaling across a multi-server network.

Modular Java plugin architecture on Spigot/Paper, Kubernetes orchestration, MySQL-backed economy systems, and web management panels.

Platform Engineering

Batlify.com

Node.jsTypeScriptREST APIsDockerTeam lead

Led a team of 4 developers building the Batlify platform. Responsible for backend architecture, technical direction, and delivery coordination across the engineering team.

Distributed backend services, REST API design, team-wide architecture decisions, and CI/CD pipeline setup. Focused on modular, maintainable service boundaries.

Developer Tooling

Modular Backend Framework for Batlify.com

TypeScriptNode.jsREST APIsArchitecture

A self-built modular backend framework for rapid service development. Designed to reduce boilerplate across microservice projects with shared infrastructure primitives.

TypeScript-first, pluggable architecture, with custom dependency injector, and built-in support for REST API scaffolding and service lifecycle management.

Infrastructure

Housing Universe - A Kubernetes-native Minecraft metaverse

KubernetesDockerArchitectureLinuxHelm

Designed and developed a full-fledged Kubernetes-native, modular solution for one of my biggest projects - Housing Universe.

Custom Kubernetes controllers, Helm charts, and IaC-first approach. Modular design with components auto-loading from S3-based configuration server.

About

How I work

I'm a self-taught developer who started by building Minecraft servers and grew into a full-stack engineer who ships real products for real clients. I care about craft — writing code that's readable, modular, maintainable, and does exactly what it needs to.

I work best in direct, async-friendly relationships where expectations are clear and trust is high. No hand-holding required.

01
Architecture before code

System design decisions compound. Getting the architecture right early reduces cost, complexity, and rewrites later.

02
Build for scale from day one

Scalability is a design constraint, not an afterthought. Modular boundaries, horizontal scaling, and loose coupling are defaults.

03
Own the infrastructure

Understanding the full stack — from application code to the underlying infrastructure — means fewer blind spots and faster debugging.

“Great software design is an art discipline — not only that it looks great, but also works. The way that a user never has to think about it.”

— personal motto
