Hi, I'm Chris!

I'm excited about everything high performance & low level programming. I work on Video Codecs, Optimization, Game Engines, Data Structures, R&D stuff, Profilers/Analyzers/Compilers/Debuggers, Rendering, Binary-Obfuscation/DRM/Reverse-Engineering-Protection, ...

Here are my favourite personal repositories & projects:

🧪 optim8.org - Online Performance Analysis Platform based on some of my other projects (zydec, execution-flow, UI, backend).

🚀 hypersonic-rle-kit - The fastest (possibly best) Run-Length-Encodings on the Planet. (Benchmarks)

🏎️ hypersonic-rANS - Some of the fastest decoding range-based Asymetric Numeral Systems (rANS) codecs. (still WIP, Benchmarks)

#️⃣ mediaLib - My main general-purpose library for larger Desktop & Graphics projects. (C++/OpenGL)

🌋 render-portfolio - Graphics & 3D Technology Portfolio/Blog. Terrain Erosion Simulation, Texture Atlases, and everything in between.

📈 silverpp - A lightweight user-mode profiler for Windows x64 with disassembler & instruction-level decompiler for hot code-paths.

🥷 llscript - A custom low-level programming language (compiler, debugger, byte-code interpreter) with shellcode-injectable runtime.

🖼️ limg - An experimental lossy image codec with a bunch of cool algorithmic & SIMD optimizations.

🩺 execution-flow - A static CPU performance analysis tool, that visualizes per-instruction resource utilization (based on llvm).

🧵 sformat - An easily-integrable, extendable, typesafe, UTF-8 compliant, non-copyleft string formatter for C++17.

🔢 ook - A simple & fast dynamically recursive Sodoku Solver. (Not SIMD, but still cool!)

🕸️ LamestWebserver - A neat Web-Server/Web-App/Web-UI framework I wrote in Uni and is incredibly easy to use.
