Backend & systems engineer · Kaunas, Lithuania

Hakan
Göksu

I write systems software in Rust and Go, and run the servers it lives on.

Most of my work sits close to the machine: a Rust desktop environment for Linux, agentic development tooling built on containers, and CLI utilities that do one thing quickly. Everything runs on infrastructure I maintain myself — all under goksu.me. I also make games.

02work

Four things I would show you first.

A desktop environment, an agentic IDE, a platform in production, and a rhythm engine that cannot afford to drift.

nx-shellLinux desktop environment

A desktop environment built as a shell layer over Hyprland, for Arch users who want something minimal, fast and visually coherent. Around 500 users in the Arch community.

FocusLog

A TUI focus timer and productivity tracker in Go. Persistent logs, statistics, category tracking. Small, fast, essentially no dependencies.

Gogithub ↗
SoulVail

Permadeath and formation-based diamond-grid combat, where souls are a moral resource you spend rather than accumulate. Skills are physical, equippable objects: Seals, Stigmas, Cinders.

Godot 4
goksu.me

Not a product — the thing everything else runs on. Gitea, a custom mail server, Nextcloud, FreshRSS, RSSHub, Syncthing and WireGuard, maintained for years across a VPS and a Raspberry Pi.

Docker Composegit.goksu.me ↗
Quick Alias

A CLI for managing shell aliases with global and per-user scope, written in C. Config management and fast setup, nothing else.

Compositors, mail servers, tunnels, audio clocks — the parts of a stack most people never open.

Backend, systems, or something Linux-shaped.

I am based in Kaunas and work remotely across Europe. Mail is the fastest way to reach me — I read it on a server I run, so it will not sit in a filter somewhere.
