Summary
👤
Senior🎓
Top SchoolJörg Wollenschläger is a Developer Technology Engineer with 12 years of experience specializing in real-time graphics, game engines, and systems-level tooling, currently at NVIDIA in Tokyo's Chiyoda district. He has deep expertise in rendering architecture and shader toolchains from his work on Enlighten and the Xenko engine, and has contributed bug fixes and feature improvements to notable open-source projects like SharpDX and the Nim compiler. His background spans research-driven robotics vision and production graphics, blending strong math and physics intuition with practical engineering. Notably, he has a track record of fixing subtle low-level issues—matrix read-backs, atomic compatibility across compilers, and model animation pipelines—demonstrating both attention to detail and systems thinking.

Back-end Developer
Back-end DeveloperContributions:47 commits, 4 PRs, 1 comment in 2 years 1 month
Contributions summary:Jörg focused on improving the SharpDX toolkit, specifically addressing issues related to skinned effects, vertex element semantics, and model animation. Their contributions included fixing matrix read-back problems, correcting semantic names, and implementing changes to model compilation for animation support. The user also introduced the CompositeTransform and refactored related classes. Finally the user refactored and fixed bugs in the model compiler.

nim-lang/Nim
Nov 2017 - Jul 2019
Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).
Role in this project:Back-end Developer
Back-end DeveloperContributions:8 commits, 8 PRs, 13 comments in 1 year 8 months
Contributions summary:Jörg primarily contributed to the Nim programming language compiler and standard library. Their work involved fixing bugs related to atomic operations within the system library, including compatibility for different compilers and architectures (vcc/cpp). They also addressed issues in the compiler related to file handling and custom pragmas, and refactored existing code related to data structures like sequences. They also updated the atomics library.
