Design and implement scalable, reusable systems such as player input handling, AI behaviors, physics, and animation states, ensuring optimal performance in diverse game scenarios.

Profile and optimize CPU, GPU, and memory usage for complex gameplay systems, minimizing frame drops and latency, often by working directly with low-level engine components (e.g., Unreal Engine, Unity).

Develop asynchronous and multithreaded systems for real-time gameplay features, ensuring smooth networked interactions in player environments.

Implement and refine physics-based interactions, collision detection, and response systems to ensure accurate and efficient physical behavior, including ragdoll effects, projectile trajectories, and environmental interactions.

Integrate platform-specific SDKs (e.g., Steamworks, PlayFab) and RESTful APIs by writing custom bindings and wrappers in C++ or C#, ensuring asynchronous operations such as achievement tracking, in-game purchases, and player authentication function correctly and are optimized for low-latency performance.

Develop and optimize HLSL/GLSL shaders for real-time rendering pipelines by implementing and fine-tuning vertex, fragment, and geometry shaders, achieving optimized lighting calculations, shadow mapping, and post-processing effects while minimizing GPU overdraw and instruction count.
