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 Lessons
A linearized library of hands-on ML lessons: RL foundations, RL post-training, Triton kernels, LLM serving (vLLM / SGLang), distributed training, generative modelling, and the durable ML interview canon.
Browse the lessons →RL Foundations
Start from MDPs, value functions, policy gradients, Actor–Critic, TRPO/PPO, RLHF, imitation learning, and continuous control.
Start the RL track →Writing
An archive of earlier posts on algorithms, systems, and engineering — design patterns, distributed systems, compilers, and databases.
