Software Engineer with 5 years of experience building real-time 3D simulation and graphics systems for defense-grade training applications at Zen Technologies (ARI Simulation). I specialize in C++, DirectX 11/12, HLSL shader development, and Unreal Engine 4/5 and Unity — having shipped full simulation modules for flight and crane simulators, built procedural image generators, and optimized rendering pipelines to significantly cut load times. Beyond graphics, I'm a capable full-stack developer: I've launched 3dthinkahead.com (React.js, Node.js, Three.js), built a React Native health app, and published a Unity mobile game suite. I've worked fully remote since 2021, so I'm experienced in async collaboration and self-directed delivery. I'm looking for a remote role in game development, graphics/simulation engineering, or full-stack development where I can own complex technical problems end to end.
