Hi, my name is Harold.
I develop 3D game engines.
I’m a Rendering Engineer focused on real-time graphics and GPU performance. I’m currently helping develop a Gaussian Renderer for XR devices, and in my free time I’ve been building the Untold Engine, a 3D game engine I’ve worked on for over 12 years.
Untold Engine Release v0.2.0-beta

About Me
I’m a Rendering Engineer passionate about real-time graphics and continuously building my expertise in GPU performance. I currently work alongside a talented team developing a cutting-edge Gaussian Renderer, pushing the boundaries of visual fidelity and rendering efficiency.
Outside of work, I’ve been building my own game engine, the Untold Engine, a fully featured 3D game engine I started over 12 years ago. For the past two years, I’ve been rewriting the entire engine from C++ to Swift, with a focus on performance, clarity, and modern graphics techniques.
Through this journey, I’ve been gaining deep knowledge of rendering pipelines, shader optimization, and engine architecture. I also share what I learn through technical articles and write-ups, which you can find below.

- Editor Tools: Scene Graph, Asset Browser, Inspector Views, Custom Components
Let’s Connect
I’m always excited to connect with companies and teams pushing the boundaries of graphics and rendering. I love the creation process of building something new and the adventure of solving problems that are still unsolved.
