At Cosoot, I led the end-to-end design of a carbon accounting platform, creating 25+ user flows, 8 major dashboard interfaces, and a design system containing 120+ components across 15 component categories. I facilitated 40+ design review sessions with cross-functional teams, conducted 15 user research sessions with industrial clients, and delivered 200+ design assets that supported tracking of 4 critical environmental metrics (emissions, energy, waste, water). The platform handled data from 5+ manufacturing facilities with 99.5% accuracy in environmental reporting.
