At Bridge for Billions, I owned end-to-end UX/UI for the incubation platform and designed Parrobot, an AI guide with conversation design in Voiceflow, adaptive onboarding and mentor handover. Alongside a PM, engineers and a content lead, I helped raise programme completion from 52% to 89%, with 78% weekly active use and answers rated 4.6/5.

At Telefónica, I designed Open Gateway, its first API marketplace, restructuring information architecture around user needs; after its MWC 2024 launch, Developer Hub visits rose 19% and drop-off during API discovery fell 17%. I now lead end-to-end product design for startups and founders, from discovery through UX/UI and developer handoff, using tools including Figma, Framer and AI prototyping tools.
