I come in at any stage and become your design lead. That means joining stakeholder calls, understanding your business goals alongside your users' reality, and helping build a product that makes sense to both. I run research and validation studies, design and iterate based on real feedback, work directly with engineers on what's feasible, and collaborate with the PM to phase work into a roadmap that holds up. I also have a seat in the release process, reviewing builds before they go out, ensuring correct implementation of the desired experience.
