Building RatUI: A Modern C++20 UI Framework
An overview of why I began building RatUI, the core architecture of the framework, and some of the technical decisions that went into it.
RatUIC++UI
C++ Graphics & Systems Programmer
Building games. Crafting custom engines, UI frameworks and graphics systems from the ground up.
I specialize in low-level systems programming, real-time rendering and creating tools that empower developers. Currently focused on building modern C++20 frameworks and game engine technology.

- →Up to 4 players local and online multiplayer
- →Physics-based damage and combat system
- →Roguelike upgrade system for losing players
- →Steam Remote Play support
- →Developed by Over-Scoped Games (team of 6, 1 programmer, 2 Designers, 3 Artists)

About
I'm a C++ programmer passionate about graphics programming, systems architecture, and building developer tools.
My work focuses on the intersection of performance and usability—creating frameworks and engines that are both fast and pleasant to work with. I believe that low-level systems don't have to be painful to use.
I've built custom rendering pipelines, UI frameworks with complex text layout, and game engine infrastructure from scratch. Each project teaches me something new about optimization, API design, and the art of managing complexity.
I also have experience shipping games commercially—most recently Clumsy Champions, a physics-based party fighter developed with my team in Unreal Engine 5. I'm comfortable working across the full stack of game development.
