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.

2020–2023

Earlier work

Mid-core multiplayer and metaverse projects at HoloNext and KobGames.

Robo Squad

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.

Hunt Heroes

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.

Kitties Metaverse

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

Hyper-casual

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.

About

How I work

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.

Right now I’m looking for my next role. If you have something interesting, reach me on LinkedIn or at cebiozgur@outlook.com.
