Hi, I'm Chris!

I'm excited about high-performance programming, low-level wizardry & complex data transformations.
Over the years I have worked on a ton of different projects including...

⚙️ Core Libraries - Allocators, Data Structures, Message Queues, Streams, Machine Learning, Cryptography, Media Handling
📦 Data Compression - Entropy Coding, Structured Data / Image / Video Codecs, RLE, LZ, Quantization Metrics
🛡️ Software Security - Binary-Obfuscation, DRM, Debug Protection, Anti-Reverse-Engineering, Dynamic Runtime Binary Decryption
🎮 Game Engines - Rendering Pipelines, Asset Processing, 3D Audio-Engine, Simulation
🧪 Various R&D Projects - Genetic Algorithms, Real-Time Photogrammetry, De-Noising, Point-Clouds Processing
⚡ Optimization - hand-tuned SIMD code-paths for specific CPUs, Cache Coherency & Memory Layout, manual Pre-Fetching
🧭 Binary Processing - Profilers, Compilers, Decompilers, Debuggers, Static Binary Analyzers

Some of my favorite public personal repositories & projects:

🧪 optim8.org - Online Performance Analysis Platform based on some of my other projects (decompiler, static-analzyer)
🌋 portfolio - My Graphics & 3D Technology Portfolio: Rendering, Erosion Simulation, UV Unwrapping, and much more...
🚀 hypersonic-rle-kit - The fastest & best-compressing Run-Length-Encoders on the Planet (specialized variants for many scenarios)
🏎️ hypersonic-rANS - Some of the fastest decoding rANS Entropy Coders (bit-stream optimized for AVX2 decoding)
#️⃣ mediaLib - My old general-purpose library for Windows-based Media & Graphics projects (C++/OpenGL)
📈 silverpp - A lightweight user-mode profiler for Windows x64 with disassembler & instruction-level decompiler for hot code-paths
🖼️ limg - An experimental lossy image codec with a bunch of cool algorithmic & SIMD optimizations
🥷 llscript - A custom low-level programming language (compiler, debugger, byte-code interpreter) with shellcode-injectable runtime
👻 paranormal-distribution - An incredibly fast & simple approximate fixed-width normal-distribution sampler
🧵 sformat - An easily-integrable, extendable, typesafe, UTF-8 compliant, non-copyleft string formatter for C++17
