What I'm looking for

I’m looking for a team where I can own core rendering and simulation performance—building editor tools, migrating/modernizing engine systems, and shipping multi-platform features with measurable speed, fidelity, and reliability.

I’m a performance-driven Core Systems and Graphics Programmer with 5 years of industry experience, specializing in real-time rendering. I’ve built and evolved systems across Unreal Engine architecture, physics engine migrations, and multi-platform deployment for PC, Console, and Mobile.

In my recent role, I architected a modular simulation backend using C++ and OpenGL compute shaders for real-time 3D cloth physics. I also developed a 3D Cloth Design Editor for interactive component stitching and data-driven iteration, and built an Angular application for high-fidelity 3D garment visualization on mannequins.

Earlier, I integrated Unreal Engine’s OnlineSubsystem across cross-platform storefronts and led a physics migration from legacy PhysX to Chaos Physics to improve simulation fidelity. I’ve also optimized iOS/tvOS toolchains and UI responsiveness, managed Wwise plugin upgrades and compatibility, and built engine-level systems like DLC ownership validation—always with a focus on reliable performance, maintainability, and tooling that empowers iteration.
