  Havok expert, performance analysis and optimization. Working on physics shapes optimizations, destruction and shape deformation in VRAGE 3 engine. Mostly using C# but also C++ for some engine parts. - physics shapes creation for deformed objects: improved performance 1.75-2.8x + spread non-critical deformations over multiple frames Havok expert, performance analysis and optimization.

• Senior Physics Software Engineer

  • Mar 2023 - Apr 2023

  Havok game physics SDK- changing the way bodies are stored (using chunked arrays instead of contiguous ones) to enable faster world cloning

• Physics Software Engineer 2

  • Jun 2018 - Mar 2023

  Havok game physics SDK Particles (low-fi rigid bodies), physics joints, character controller, Unity integration (GameObjects and DOTS/ECS); used C++ mostly (without std lib), C# sometimes.Features:- deactivation in particle-particle collisions (making particle piles steady) - particles are simulated similarly as rigid bodies, just lower fidelity and better performance- mentored an intern who improved performance of deterministic particle-particle collisions- compound shape memory optimization- multiple physics worlds in Unity Physics and Havok Physics for Unity- primary dev working on Unity Physics and Havok Physics for Unity in some periods- owned the integration of Havok constraints into Unity (GameObjects and DOTS) and helped Unity's physics team with motorized joints v1 in Unity Physics- auto-climbing on obstacles for character controller (and comparison vs PhysX), developed on top of Havok's ProxyCharacterController- switching from quantized to float AABBs for bodies- various fixes for clients, like penetration prevention in ProxyCharacterController when other bodies have high velocities Show less
