Game and editor systems
The in-game editor, object interaction, Rumi movement, collection systems, and the UI tying those parts together.
Summary
Armin Grbić
Senior Game Programmer
I've always wanted to make video games, and I've been interested in every part of how they're made. Learning across those disciplines has given me a broad range of skills, though programming remains my main focus. On my own projects I also handle design, art, animation, UI, and the work involved in bringing a game to a store.

Current project
MiDiO
MiDiO is a room-building and creature-collecting game. Players create small 3D dioramas, populate them with Rumi, and share their rooms through Steam Workshop. Twitch and Firebase integration let viewers participate in its collection systems without owning the game.
MiDiO is available to buy and play on Steam in Early Access. I develop it solo, covering the game, editor, UI, integrations, art and content, and ongoing production.

Data and player content
Persistent rooms, scene reconstruction, player images, previews, imported content, and Steam Workshop sharing.
Services and platforms
Steam features, Twitch integration, backend services, local file handling, and the UI built around them.

Side project
EUC
EUC is a chaotic online co-op game for 2-4+ players, with PS2-style graphics. It is a game I'm actively developing and a side project for learning, expanding my portfolio, and exploring new ideas.
Like MiDiO, I'm building almost everything myself: programming, design, art, animation, UI, and tools, with some third-party assets and plugins.
Multiplayer
Steam sessions, replicated gameplay, server-side state, and shared player interaction.
Gameplay and structure
Cooperative gameplay, player interaction, progression, and shared game state.
Interface
Menus, lobby, HUD, results, and the flow between each part of a session.
Environment and tools
PS2-style art direction, environments, and reusable construction tools.

Professional experience
Game programming in production
At 2tainment, I worked across gameplay, simulation, UI, databases, and tools in an established football-management codebase. My work included developing features, maintaining existing systems, and supporting releases.

Small projects
Self-contained games built over a few days to a little over a week, in the spirit of a small game jam.
Yoon (Unity) - Made in a little over a week. A small game about a streamer trying to make it big, earning money for a better PC, with a gacha system and WarioWare-style minigames.
Miploons (Unity) - A Bloons TD-inspired clone made over a few days, with Twitch integration that lets viewers trigger enemy waves and boss encounters.
Additional disciplines

2D and 3D character work, sculpting, textures, rigs, animation, and engine integration.
Shaders, VFX & engine tools
Materials, shaders, visual effects, and tools in Unreal Engine and Unity, including workflows for building environments and working with game assets.
Modding & Misc.

About
Background and skills
I'm Armin Grbić, also known as Schira(Dev), a game developer based in Berlin. I have spent more than ten years making games, including around six professionally, across solo projects, collaborative games, and commercial production.
Programming is my main discipline, with hands-on experience across design, art, and production. Most of my projects are maintained in private Git repositories. I can discuss their implementation and share code examples where I have permission.
