I’m a senior machine learning engineer building scalable training and inference systems. At Block, I work on high-throughput model serving, deep learning training frameworks, and ML infrastructure that makes models faster, cheaper, and easier to ship.

Previously, I led medical imaging ML work at Maxwell Plus, building 3D MRI segmentation systems and publishing prostate cancer risk modelling research. Outside work, I build data-heavy products like The Boxing Book, a global amateur boxing database tracking 40k+ fighters.
