I typically work with a designer or design team, but I can work directly from a mockup or a loose description and a brand guide as well. Based on the visual input and your goals, I'll build out the desired surfaces, behaviors, integrations, etc. with the project goals and constraints in mind. When the work is ready, you'll have time to review and approve it.

Just about everything I do comes with attention to detail, consideration for maintainability, and the flexibility for being iterated on in the future by me or another developer.
