Experience

SpaceCatch

https://spacecatch.io/
Worked as the Unity lead developer on SpaceCatch, an ambitious AR mobile game connected to the cryptocurrency world, inspired by titles like Pokémon GO. My role spanned both leadership and hands-on development. I led a small team of Unity developers, maintained high code quality standards, and proposed scalable technical solutions. I was responsible for designing and implementing the core architecture, covering both front-end (Unity, C#) and back-end systems using PlayFab and Azure Functions.

Beyond programming, I played an active role in crucial game design discussions that helped shape key gameplay mechanics. I collaborated closely with game designers, graphic artists, and QA to ensure smooth integration across all areas of development. The project also gave me the opportunity to refine my leadership skills and apply modern Unity technologies to a real-world commercial mobile game.

Shootvaders: The Beginning

https://store.steampowered.com/app/1819900/Shootvaders_The_Beginning/
Developed a frenetic space shooter with gameplay rooted in old-school arcade games. It involved taking your ship on the journey through the endless space, destroying enemies, and staying alive as long as possible. It includes online score tables and local co-op.

The game was developed for Went2Play (went2play.com), and I contributed to the programming and partial game design. Development involved using Unity engine, C#, and third-party libraries, such as Steamworks, Google Play, and Unity Ads.

The game was made available on Steam.

Afraid

https://gamejolt.com/games/afraid/95840
Developed the entire game, including game design, programming, and graphics. Afraid is a logical adventure game where the goal is to stay with the light and therefore stay alive. The darkness was the enemy in this small game.

Afraid was developed in Unity, and unlike my other games, it contained a short narrative-driven story. It was one of my first game creations.

Block Buster HTML5 Game

https://prizes.gamee.com/game/blockbuster
I created a game called Block Buster during my working experience at GAMEE. It's a simple HTML5 game where you smash blocks, avoid enemies, and collect coins.

The game design was my idea, and I completed all the programming in the Cocos Creator engine. The game's HTML5 nature made it playable on PC through the web and mobile devices.

Fantasy Finger Football

Co-developed this multiplayer mobile game with a gameplay similar to pool games. Collect the team of heroes with unique abilities and defend your enemy in PvP and PvE battles!

This game was created as contract work for NoxGames, and I was in charge of the gameplay and menus programming. I was the leading developer for multiplayer core, using the Photon framework for Unity, and I co-programmed back-end functionality based on Playfab game services.

Bounce Bounce, The Couch!

https://gamejolt.com/games/bounce-bounce-the-couch/171122
Fully designed and coded this crazy arcade game about two guys holding the couch, which can bounce the other people into the space. To save the world, you must bounce as many people as possible. But beware the big guys! They are heavier than the others, and they can break your couch!

Entirely made in Unity under my label, Collective of Crab, in cooperation with graphic artist Anna Benesova. My work included full game design, complete programming (menus, gameplay, third parties integration), UI, and particle effects creation. The crazy idea of the game came from the game jam, where the main theme was "couch."
