Senior product designer working where machine intelligence meets operational work. Since 2019 I've led end-to-end design for enterprise platforms and AI products — scalable design systems, ML-integrated workflows, and internal tools measured in cost savings and developer throughput rather than impressions. Happiest on a hard problem with a good team.
