Rockstar🎓
Top SchoolMikael Hermansson is a software engineer with 11 years of experience specializing in game engine physics and tools, currently contributing to W4 Games and the open-source Godot Engine. His backend work on Godot and the godot-jolt extension shows deep expertise in physics systems—adding soft body simulation features, collision exclusion, inertia control, and new shape support. He has shipped engine and tooling code at major studios including Frostbite and Avalanche, and has experience founding and freelancing in the games space. Based in Greater Stockholm, he blends production game development with impactful open-source contributions to a high-profile project used across the industry. An unusual strength is his focus on low-level physics correctness and integration, not just gameplay scripting, which makes him valuable for engine-level challenges.

Godot Engine – Multi-platform 2D and 3D game engine
Role in this project:Back-end Developer
Back-end DeveloperContributions:121 reviews, 7 commits, 86 PRs in 3 months
Contributions summary:Mikael's contributions primarily involve modifying the Godot Engine's physics server and related systems. They implemented new methods for disabling collisions between joint bodies and for excluding bodies from physics queries. Further, the user added methods and properties for soft body simulation and made the physics servers end their synchronization on exit. These changes indicate work focused on improving the engine's physics capabilities.
