React & Next.js Engineering
in London

Production frontends shipped on a flat price.

We ship production React and Next.js applications for founders in London. App Router, server components, type-safe APIs, real performance budgets. A senior engineer owns the frontend so you don't end up with a Storybook full of components and nothing live.

What you get

Concretely, by the time we hand over

  • Next.js App Router project with server components and streaming
  • Type-safe API layer (tRPC or typed REST) — no runtime shape surprises
  • Component system aligned with your brand (or shadcn/ui composition)
  • Real-world performance — Lighthouse 90+ on the routes that ship
  • Deployed on Vercel with preview URLs for every branch

Why this works for London

The local math

London is the #3 startup ecosystem globally and the gateway to European pre-seed. Hiring senior engineers means £100K+ packages and 90-day cycles in a market still recovering from the post-Brexit shuffle. We work async with London founders, bill in USD, ship in two weeks.

Year-one outlay for a single senior hire in London: ~$200K. Our react & next.js engineering engagement starts at $6,000.

Why us

Why founders in London pick us for this

  • 01

    Day-one React, day-one Next.js — we don't learn the framework on your project

  • 02

    Server components and partial prerendering used where they help, not as a cult

  • 03

    We know which patterns to avoid (Context-as-state, useEffect overuse, prop drilling)

  • 04

    Flat price covers QA on real devices, not just 'works on my Mac'

FAQ

Common questions about react & next.js engineering in London

How fast can you start?

+
Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.

Is the price really flat?

+
Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

Pages Router or App Router?

+
Default to App Router for new builds — server components, streaming, Cache Components, and the routing primitives are where Vercel and the framework are investing. We migrate Pages → App on request.

Can you work with our existing backend?

+
Yes — REST, GraphQL, gRPC, your homegrown JSON-RPC. We wrap it in a typed client and the frontend doesn't care about the protocol underneath.

Who owns the code?

+
You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
