Lead game developer · Romania

Gavriil
Bidasca

Lead developer at XOX Studio, making live Roblox games since 2021.

On the studio's first games I was usually the only programmer. Now I coordinate a team of about 15 and review their code, and I still write a lot of it myself: gameplay, UI, player data, and exploit fixes on live servers. At their peak, the studio's games had about 25,000 players online at once.

Looking for gameplay, systems or tech lead roles. Based in Romania, working remotely, open to relocating.

How I got here

I learned development by fixing things I didn’t understand yet. At fourteen, that meant broken MTA roleplay servers, unfamiliar Lua, and a lot of reading other people’s code until the errors made sense.

I still work that way. At XOX I went from building the first games mostly on my own to coordinating a team and keeping several live games healthy. Some weeks that’s gameplay code, some weeks it’s UI or models, and some weeks it’s chasing down an exploit that showed up overnight.

Long term, I want to make original, story-driven games. The engine and hardware projects further down are how I keep learning outside of Roblox.

Games I’ve worked on

Studio work, contract work and my own prototypes.

Outside of work

Most of these started because I wanted to know how something worked.

In progress

M32: 32-bit Intel Mac apps on Apple Silicon

Apple Silicon Macs can’t run old 32-bit Intel apps at all. M32 loads the original binaries and translates their system and graphics calls into native ones so they can run again.

Unity / Godot

Unity and Godot prototypes

Small gameplay prototypes and GLSL lighting shaders, mostly to learn how other engines do things Roblox handles for you.

Where I started

GTA multiplayer mods

MTA and SA-MP servers were where I actually learned to program: broken roleplay scripts, Lua I didn’t understand yet, memory hooks, and fixes I found by reading until the code made sense.

C++ / Lua
Microcontrollers

ESP32 and RP2040

Display drivers and small telemetry gadgets in C++. With a few hundred KB of RAM, you notice every bit of overhead.

C++ / SPI / I²C
Old hardware

Linux on ARM tablets

Running Debian on old Android tablets, with touch input, custom configs and a small system monitor I wrote for them.

Linux / ARM
Tooling

Local AI tools

Small scripts with Ollama and MCP that help with my own development work and run on my machine.

Get in touch

I’m looking for a full-time gameplay, systems or tech lead role, and I also take contract work on multiplayer games. Email is the quickest way to reach me.
