From design handoff to shipping: a quality bar for web UI
How I turn Figma frames into resilient components, performance budgets, and accessibility checks that survive production traffic.
- Next.js
- Accessibility
- Performance
The handoff is not the finish line
Design files rarely encode every state: loading, empty, slow networks, and keyboard-only flows. I treat the handoff as a contract—not a screenshot—and extend it with edge cases the product will inevitably hit in the wild.
What “done” means on my side
- Semantic structure first, then motion. Screen readers and search engines benefit from the same hierarchy users perceive visually.
- Performance budgets early: largest contentful paint and interaction targets are negotiated before the UI is “pixel perfect.”
- Component APIs that match how teams actually extend the system—props, composition slots, and documentation that stay in sync with code.
Closing the gap with engineering
The strongest interfaces come from short feedback loops between design and implementation. I prefer small, reviewable PRs over big-bang drops, so regressions are easy to spot and roll back.
If you are planning a new surface—dashboard, marketing site, or checkout refresh—clarity on priorities (conversion, speed, accessibility level) saves weeks downstream. That is the conversation I like to start with.
