Lewis Watling

I design and build AI-first products from 0 to 1. Most recently in mental health and wellbeing.

Currently leading design at Sylva.

Sylva

Designing an AI support app that helps parents of neurodivergent children understand their child and find the right support.

Designing a cover management platform that takes the morning scramble out of arranging staff cover for UK schools.

“Lewis is among the top designers I’ve ever collaborated with.”

A simple loop: sketch, explore, build, learn. These are the tools I reach for along the way.

01
Receive The Brief
I start on paper. Sketching ideas out the old-school way is the quickest route to a good first idea.
02
Explore Options
When time is short, I take the sketches into Claude Design for something quick. With more time, I open Excalidraw and work through options.

Build In Figma
Wireframes go into Figma. If we need components, I build them there, then design the screens with Claude alongside.

Learn From Users
PostHog or UXCam to see how people really behave, then user interviews to find out why.

How I Use AI
Agents write tickets from the designs, check what is built against the design system and our compliance documents, and test the live app. I review everything, and agents check each other’s work.
