Marie-Astrid Molina discusses her experience designing products for Scaleway, a cloud computing company, as someone unfamiliar with the technology. She took three steps: 1) Not panicking and gaining a basic understanding by testing interfaces and comparing to competitors. 2) Finding "lighthouse" experts to learn from through references, filtered medium, and redrawing concepts. 3) Ensuring long-term efficiency by establishing common language, design reviews, and never assuming knowledge to avoid mistakes. Her goal was to bring a positive experience to clients despite initial lack of expertise in the subject area.
