UI/UX design is the planning and drawing of the screens themselves before a line of code is written. I map out what each person needs to do, sketch the structure as wireframes, then design the full-fidelity screens for phone and desktop and link them into a clickable prototype you can test with real people. The developer gets a Figma file with every state, spacing rule, and component defined, so what ships looks like what you approved. It's the design half of what my web development and custom software work builds, and it works just as well when another team is doing the coding, whether you're down the road in Iowa or working with me remotely from Missouri or Illinois.
