Software engineer since 2013, working across mobile, backend, and frontend before going all-in on open source. Since 2021 I maintain Storybook at Chromatic — focusing on testing, developer experience, and AI-assisted workflows — and I love sharing what I learn with the community through talks, docs, and courses.
