Machine Learning Engineer
Hi, I'm Jacob.
I'm a machine learning engineer working on machine-learning systems and RL — training and serving large models, GPU kernels, and the infrastructure around them. I like understanding systems from first principles and writing the explanation I wish I'd had.

ML Fundamentals
A first-principles reference library: ML & deep-learning foundations, generative models, reinforcement learning, GPU kernels & LLM serving (CUDA / Triton / vLLM / SGLang), distributed training, and systems design.
