This is our second project with this designer. Mademoiselle B was every bit as involved as she was in the first one, and then some.
Her ability to proactively think through workflows and ask pertinent questions has had a very positive impact on the project, helping us cover a lot of ground in a short period of time.
User experience depends on developer experience as well, as a design mustn't just be fancy but lend itself to Extensibility. Mademoiselle B was mindful of this throughout, made essential pauses at significant moments to confirm implementation-viability from a development standpoint, and provided additional annotations as necessary.
Overall, it was a smooth, productive, world-class experience.
