I’m a freelance Next.js and React developer based in Coventry, UK, working 25–30 hours a week — mostly for design-led studios and agencies who’ve won more than they can staff.
I build marketing sites on headless CMS (Sanity, Storyblok), web applications with real data and auth, and dashboards that stay fast and accessible under load.
Recent work: a booking platform with a real availability engine and a staff-side schedule (Next.js, Postgres), a magazine site on Sanity with live draft preview, and an analytics dashboard tested by screen reader as well as by eye. All three are measured, not just built — Lighthouse, axe-core and CLS numbers are in each README, not just claimed.
Happy to start with a small paid trial before anything client-facing. White-label as standard: NDA and non-solicitation signed up front, no trace of me in the deliverable, your client relationship stays yours.
Portfolio: rhysllewellyn.dev — every case study links to the live build and the repo.

A magazine site built on Sanity: a content model an editor can use without a manual, side-by-side draft preview on the live site, and revalidation driven by a publish webhook rather than a timer. Self-directed demonstration build, not client work. Live: fieldnote.rhysllewellyn.dev · Source: github.com/RhysLlewellyn/fieldnote
A dense SaaS dashboard over 4,000 seeded customers: server-side filtering and paging, a cohort grid, and charts that stay readable at 360px and in greyscale. Tested by listening to it with a screen reader. Self-directed demonstration build, not client work. Live: ledger.rhysllewellyn.dev · Source: github.com/RhysLlewellyn/ledger
A booking system for an invented physiotherapy clinic: a multi-step booking flow with URL-addressable state, a real availability engine, and a staff-side week schedule. All nine routes render real content with Postgres stopped — proven, not assumed. Self-directed demonstration build, not client work.
