OPEN TO WORK

I build stuff that
actually runs.

Computer-science student & automation developer from Slovakia. I deploy what I build after extensively testing it and finding bugs some would dismiss as intended.

Things I’ve built & shipped

G.U.I.D.E. Codex — character dossier screen ★ FLAGSHIP

React TypeScript Supabase

G.U.I.D.E. CODEX // OPERATOR CONSOLE

A custom character-management web app for a tabletop campaign — part character sheet, part DM control panel — themed as an in-world neural implant that’s secretly the campaign’s villain.

Players spend the whole game inside a helpful-looking interface that’s quietly watching and corrupting them — dramatic irony baked into the visuals. The player side is cyan and reassuring; amber is the “system-truth” color that leaks through in unsettling moments. The DM console is amber-forward, because that’s where the truth lives.

Python Anthropic API Oracle Cloud

AI Calendar Assistant

An end-to-end assistant that manages my calendar through natural-language Telegram messages — deployed, running under systemd, and debugged in production.

Built with Flask and the Anthropic API (Haiku), integrated with Google Calendar via OAuth. Deployed on an Oracle Cloud free-tier VM (Ubuntu 22.04) under systemd, with Tailscale for secure remote access. The fun part was the real production debugging: OAuth token expiry, Node version conflicts, and switching providers to beat rate-limiting.

C# / IL dnSpyEx

Mod Engineering

Deep technical work on a community character mod — patching compiled C# assemblies at the IL level and hunting down a subtle multiplayer desync.

Fixed localization by patching hardcoded string literals at the IL level inside compiled C# assemblies using dnSpyEx — no source access. Then diagnosed a multiplayer desync caused by non-deterministic RNG consumption flowing through a non-networked field, and reported the findings back to the mod authors to fold upstream.

NeoForge Lua

Server Hosting

Set up and ran a private NeoForge (Minecraft) server for 4 friends, and built in-game computing projects with CC:Tweaked. Server admin, Lua, systems design.

05 worldbuilding

Brettany

A long-running D&D worldbuilding project — lore across military, religious, trade and infrastructure systems, plus a homebrew class. Built to welcome friends new to the hobby. Systems design, writing, docs.

How I work & what I’m about

1

I finish what I start. Leaving things undone breathes down my neck — I can’t stop thinking about it until it’s done.

2

If something needs a deep fix or a deep dive, I’ll do it. I like looking at systems from the inside — how they work, and why they don’t.

3

I sweat the details and ask a lot of follow-up questions. If something’s missing, I ask what it needs — then I build that too.

“I like systems I can take apart, understand, and rebuild better.”

BEYOND CODE

A tinkerer outside of work too. Modding makes me happy - when something breaks I debug it, write fixes, and report findings back to mod authors. I build an elaborate world for the D&D campaigns I run, and I’m into hardware: PC builds, keyboards. Usually with music on.

04 / SAY HELLO

Got a system worth
taking apart together?

Open to internships and side projects — automation, self-hosted services, or anything that needs someone who’ll actually finish it.
