About Me

I'm a game developer building gameplay systems, editor tools and real-time interactive applications with Unreal Engine 5 and C++. I design modular, data-driven frameworks for input, inventory, UI and game settings, with a focus on clean architecture and designer-friendly workflows.

Optimizing rendering performance and building production pipelines and update systems are a big part of my work too. I publish the Unreal Engine plugins I build on Fab and back them with documentation, setup guides and usage examples on GitBook and YouTube.

  • Gameplay Systems

    I build modular, extensible gameplay mechanics in C++ and Blueprint.

  • Editor Tools & Plugins

    I create documented Unreal Engine plugins and editor tools, published on Fab.

  • Performance Optimization

    I tune foliage, lighting and rendering setups for smooth experiences.

  • Pipelines & Update Systems

    I speed up production with asset pipelines, launchers and DLC / patch systems.
