What I'm looking for

I'm looking to build performant gameplay, combat AI, physics, and engine systems in Unreal Engine, collaborating closely with designers to refine player feedback, interactions, and combat.

I am a Game Developer and Software Engineer specializing in C++, Unreal Engine, and real-time graphics/physics simulation. Over the past few years, I have engineered AI systems, custom physics models and gameplay frameworks for shipped titles on Steam and various indie projects.

My technical background spans low-level C++ (multi-threading, spatial partitioning, compute shaders) as well as higher-level engine systems like Unreal Engine (Blueprints, Behavior Trees, Niagara) and Unity.

I am driven by building modular, high-performance C++ architectures and scalable gameplay mechanics, with a strong focus on spatial algorithms, performance profiling and real-time execution loops.
