Amazon

• Build the agentic design tooling ~40 teams use to ship one shopping surface against Amazon design systems — generated from a prompt, not hand-coded.
• The public version of this problem is Luthier, three roles down.

Void Industries

• Built a real-time collaborative game engine, four engineers, pre-launch.

Amazon

• Cut add-to-cart latency from 300ms to under 50ms with optimistic updates, and designed the interaction as a component every add-to-cart surface reuses.
• Shipped the first Rio Design Tokens, the token layer the Amazon app themes from.
• No designer was assigned to that interaction, so I designed it — the choreography, the easing curves and the timing — and reviewed it with a principal designer. It launched on the homepage and Buy Again.
• One source of truth for colour, type and spacing across iOS, Android and web.

Amazon

Marketing graphics, Amazon worldwide. Lead FE, team of five.

• Took Composer from 5,000 to 50,000 graphics a year. Built Luthier, a no-code template editor, and a Figma plugin that turns a designer’s file into a template.
• Built Brand Builder: 100 templates per brand across 30+ brands, 3,000+ in all, against 20 a year hand-coded.
• Launched A/B tests on Amazon retail pages worth $100MM+ annualised; the largest raised product image size on Fresh: +$85.4MM, +0.67%.
• A hand-coded template took weeks, and only its author could change it.
• Migrated the rendering engine from Canvas to HTML, making a new template 5× faster to create, and cut initial image load 75% (5s to 1s) by profiling loads and caching repeated calls.
• The Fresh test result held at 99.88% probability of positive return. Led ideation, requirements, prototyping, usability testing and both ends of the build.

Microsoft

• Shipped the PowerPoint Pen Toolbox after 20-plus prototype rounds in code, with an A/B test settling the final design. Shared components used by 100M+ people.
