Don D. Le

COMPUTER ENGINEER & SOFTWARE DEV

I'm an engineering student @ UCLA with experience in low-latency system programming, ODEs/PDEs modelling, and computer vision.

Languages: C++, C, CUDA, Python, Rust, Assembly [x86], LaTeX, JS, Java

Tools: CMake, GNU Make, Boost, GCC, MSVC, vcpkg, SIMD, Conda, Docker, Linux, WSL2, CUDA Toolkit

I place a major emphasis on efficiency, performance, and speed; especially in my work with graphics and image processing, embedded systems, and physics simulation. I also do web dev (sometimes), where I value simplicity and minimalism.
