Frontend Developer, React / Next.js (Freelance)

Job description

Engagement: Freelance / contract only

Workload: Depends on the project — typically 4–12 weeks per project, with repeat work

About the role

We design product interfaces and marketing sites for SaaS, fintech, e-commerce and Web3 clients. A growing share of them can't be built in Webflow — headless storefronts, design-system implementations, high-motion sites, component libraries handed over to in-house engineering teams. That's where you come in.

You'll work from Figma files our team produces, with direct access to the designers.

What you'll do

- Build production frontends in React / Next.js / TypeScript from Figma designs

- Implement design systems in code: design tokens, component libraries with full variant and state matrices, dark and light themes, Storybook

- Work with and extend shadcn/ui + Tailwind setups — several clients run this stack and expect designs to map onto it without custom CSS

- Build headless frontends against client-provided APIs and CMSs (Sanity, Storyblok, Contentful), including e-commerce storefronts with search and faceting (Algolia) and payment integrations (Stripe and similar)

- Implement complex motion: scroll-driven transitions, parallax, GSAP ScrollTrigger, Framer Motion, Lottie — at 60 FPS with GPU-accelerated transforms

- Build data-dense UI: dashboards, tables, filters, charts (Recharts, D3)

- Deliver responsive down to 320px with accessibility basics covered

- Hand off documented, prop-typed components the client's engineers can pick up

- Produce hours-based estimates for incoming leads within 24–48 hours

Must-have

- 4+ years commercial frontend; strong React + TypeScript

- Next.js in production: App Router, SSR/SSG, routing, data fetching

- Tailwind CSS, and experience mapping design tokens from Figma into a Tailwind config

- Component library work: variants, states, sizes, composition, documented props

- Real animation experience, not just CSS transitions — GSAP or Framer Motion in production

- REST/GraphQL integration with proper loading, empty and error states

- Git, code review, clean commit hygiene

- AI-assisted development. Claude Code (or equivalent) is part of how you work day to day — scaffolding components, refactoring, writing tests, exploring unfamiliar APIs. You can go from a Figma screen or a brief to a working clickable prototype fast, using AI to compress the first 80%, then take it to production quality yourself. You review AI output critically and don't ship it unread.

- English B2 or higher — you'll join client technical calls

- Security judgement: we regularly receive leads asking us to clone and run their repository. You must be able to recognise suspicious code and refuse to run it — this came up four separate times in 2026.

Nice to have

- shadcn/ui and Storybook

- Headless CMS: Sanity, Storyblok, Contentful, Strapi

- E-commerce at scale: Algolia, faceted search, large catalogues (1M+ SKUs), Stripe and regional payment providers

- Three.js, WebGL or React Three Fiber for 3D web experiences

- Vercel deployment and Core Web Vitals optimisation

- Web3: wallet connect, contract reads

- Ability to also work in Webflow for hybrid projects

Soft requirements

- Product thinking: you challenge a design if it will be slow, inaccessible or unmaintainable

- Comfortable working directly with designers, not just tickets

- Clear async written communication

Application

Send 2–3 live projects with your role described, a link to a component library or Storybook you built, an example of a prototype you assembled with AI tooling, your rate and availability.
