Yoan Rock

My name is Yoan Rock, an Unreal Engine developer specializing in Gameplay Programming, UI, and system architecture in C++ & Blueprints.

For over 5 years, I have been working on AA and independent projects with Unreal Engine 4 & 5, collaborating with several studios such as PLAYERUNKNOWN Productions, Game Atelier, Limbic Entertainment, Chillchat, and Cyanide. I participated in the development of several released games, including Park Beyond and Otherskin.

I specialize in:

- Gameplay Systems

- UI/UX with UMG, Slate, and CommonUI

- Scalable and maintainable architecture

- Unreal project refactoring

- Optimization and debugging

- Blueprint to C++ conversion

- Gameplay/UI integration

- GAS (Gameplay Ability System)

I enjoy building clean, modular, and long-term maintainable systems. My approach is based on simple principles:

- clear separation between gameplay, UI, and data,

- reusable widgets,

- readable code,

- scalable architecture,

- strong focus on user experience and gamepad/keyboard-mouse support.

Notably, I led the complete redesign of several UI systems under CommonUI, drastically reducing navigation/focus bugs and significantly improving team debugging speed.

In parallel to freelancing, I also do Unreal Engine mentoring and help developers progress on topics such as gameplay architecture, UI, C++, production best practices, and technical interview preparation. And I am in the process of becoming a UAT with Epic Games.

If you are looking for an autonomous, quality-oriented Unreal developer capable of handling complex systems from end to end, I would be delighted to discuss your project. 🚀
