Worked with project teams to create user-friendly and appealing application interfaces and websites for users. Met with project manager, business analyst and architect right from beginning of project, creating rough mock-ups that were refined and extended over many iterations. Once development was underway, made adjustments to mock-ups as necessary to address problems encountered by developers. A few weeks (or sometimes days) before "go-live" dates, performed detailed quality reviews of the developed apps to ensure fidelity to mock-ups.
