Unity game developer in Istanbul
I take games from an empty project to a live product and stay with them — six years across mid-core, hybrid-casual and hyper-casual titles.
Spektra Games, 2023–2026
Two live titles I built and operated, from first commit to millions of players.
Founding engineer on gameplay, physics and tooling
#1 Racing on the US App Store at launch in the US and 45+ countries, and the category’s most-downloaded title since. Featured by Apple in “Games We Love”.
How it was built
Gameplay & performance engineering
A live open-world driving title with 15M+ downloads, where I built customization, events and game modes, and kept it smooth on low-end hardware.
How it was built
Personal project, open source, 2026
Four mobile puzzle games on Tileworks, a modular Unity framework for tile-based puzzle games that I wrote on my own time to show how I design and write gameplay code. It is not a shipped product: no players, no metrics, and the art is AI-generated placeholder work.
2020–2023
Mid-core multiplayer and metaverse projects at HoloNext and KobGames.
Mid-core multiplayer battle royale. I built the character system, skills, spectate mode, minimap, kill feed, trophy and mission systems, matchmaking and AI, plus the client side of the game APIs.
Mid-core co-op multiplayer with 15+ playable characters, each with a unique attack ability. I owned gameplay programming, real-time networking, AI, matchmaking and mission tracking, along with IAP, Play Store, Game Center and Facebook login integration and release.
A WebGL open-world metaverse built in Unity and Photon Quantum — 128 concurrent players per room, with 4000+ playable characters assembled at runtime from on-chain data. Players link a wallet, explore, chat and join PvP battles, on web and mobile.
27 solo titles
The 27 titles below I developed solo at HoloNext and KobGames, on top of a modular, extendable gameplay codebase I engineered to make new prototypes fast to stand up. I contributed to 15+ more by mentoring junior developers or managing the project. Most have since been delisted — hyper-casual titles are sunset once their live window closes.

IEEE TUAC, 2021
Built a shooter environment to benchmark two AI architectures head to head across varying agent counts and maps, then presented the results at the IEEE TUAC conference.
I’m a Unity developer with six years on live mobile games, most recently as one of the first two engineers on Highway Racer Pro. I work across whatever the game needs — gameplay, physics, AI, networking and tooling — and I build from modular architecture and its documentation outward, automating what would otherwise be done by hand.
I’ve worked on-site, hybrid and fully remote over the past six years.
Right now I’m looking for my next role. If you have something interesting, reach me on LinkedIn (opens in a new tab) or at cebiozgur@outlook.com.

Side project, just for fun
A little multiplayer game I made in my spare time: cats playing blackjack, roulette, poker and slots
in a seaside casino. It runs in your browser on desktop or phone, and everyone who drops in plays
in the same room. Under the hood it is Photon Fusion with up to ten cats per room.
