About

I’m a performance engineer focused on squeezing every last cycle out of GPU workloads. My interests span high-performance computing, deep learning optimization, and computer architecture — pushing state-of-the-art models to peak performance across speech recognition, machine translation, image classification, and generative AI.

This blog is where I document my learning notes in my spare time: GPU performance insights, source code deep dives, and hard-won optimization techniques. I also build developer tools in Python, CUDA, and PyTorch to make deep learning research faster and more productive.
