You know what the platform can do and you stay current on what's new * Is fluent in the web animation stack - from CSS transitions to GSAP to the Web Animations API - and knows which tool fits which problem. Understands that motion on the web is a performance concern as much as a design one. * Is proficient in React and Next.js, particularly in a content-heavy, pre-rendered marketing context. * Has experience working within and extending a design system, with pragmatic opinions about when to use what's there vs. when to build something new. * Has worked closely with brand designers or creative directors in previous roles and knows how to navigate strong design opinions. * Cares about performance as an extension of craft: a slow or janky interaction isn't just a technical problem, it's a design failure. * Has experience with DatoCMS or a comparable headless CMS. ## Related Videos - [GraphQL + Apollo + Next.js: A Lovely Trio](https://www.wearedevelopers.com/videos/311-graphql-apollo-next-js-a-lovely-trio) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [The Resilience of the World Wide Web](https://www.wearedevelopers.com/videos/1281-the-resilience-of-the-world-wide-web) - [WeAreDevelopers LIVE - CSS is DOOMed](https://www.wearedevelopers.com/videos/1851-wearedevelopers-live-css-is-doomed) - [From Zero to Hero: NextJS 13 and Tailwind CSS for Beginners](https://www.wearedevelopers.com/videos/766-from-zero-to-hero-nextjs-13-and-tailwind-css-for-beginners) - [NoLoJS - Avoiding JavaScript Cruft with HTML and CSS - Aaron T.
