Full Stack Developer in London

Arcode works as a focused full stack developer for teams in London. If you are searching for a full stack developer in London, you probably want a studio that designs, builds, and launches rather than one that only presents slides.

  • Complete product delivery
  • API and database design
  • Auth, billing, and realtime

Frontend to backend, one owner

Hiring rounds often take weeks before anyone writes real code. What you usually need is one person who can own the architecture and the delivery from the first week.

You talk directly to the people writing the code, which keeps architecture decisions close to the implementation.

We work best with founders and teams needing full-stack ownership who want a partner that ships. UI, APIs, auth, payments, and infrastructure delivered as a coherent product system.

What you get

  • Complete product delivery
  • API and database design
  • Auth, billing, and realtime
  • Maintainable TypeScript codebases
  • One studio accountable for the result
  • Design and engineering on the same schedule
  • Support available after launch

How engagement works

As your full stack developer, we run a shared backlog, design reviews, and engineering sprints, and you keep one point of contact throughout.

  1. 01

    Discover

    Goals, constraints, data sources, and success metrics, all settled before we touch architecture or prompts. Nothing here waits on a handover between separate teams.

  2. 02

    Design

    System design, AI/tool boundaries, interface direction, and interaction prototypes. On full stack development projects we favour practical architecture over trendy defaults.

  3. 03

    Build

    Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. The work for teams in London stays tied to the outcome you asked for.

  4. 04

    Launch

    Ship, monitor, harden, and keep improving models, tools, and product after go-live. You see progress on the critical path every week.

How we build it, and why

The stack is chosen per project, not applied from a template. For full stack developer work these are the defaults, and the reason each one is on the list.

React
the component model most teams can already hire for and maintain
Next.js
server rendering and static generation in one framework, so marketing pages stay fast and app routes stay dynamic
Node.js
one language across the stack, so context does not get lost at the boundary
NestJS
structure and dependency injection on the backend, which keeps a growing API from turning into a pile of route handlers
Stripe
payments, subscriptions, and the tax and invoicing edge cases you do not want to build

What the first weeks look like

  1. Days 1-3

    Context and constraints

    Codebase, deploy path, and what "done" means for the full stack development. Short, because the useful version of this is specific.

  2. Week 1

    First shipped slice

    Something real goes out in the first week — complete product delivery rather than a setup ticket.

  3. Weeks 2-6

    Build to the milestone

    Pull requests, reviews, and weekly demos. You see the work as it happens rather than at a handover meeting.

  4. Handover

    Documented and transferable

    Runbooks, architecture notes, and a walkthrough, so the work does not depend on us still being here.

Weighing up your options

There are three realistic ways to get this built. Each is the right answer for someone.

A solo freelancer

Cheapest per hour and fine for a contained task. The risk on full stack development is breadth — one person covering design, backend, infrastructure, and launch usually means one of them is weak, and there is no cover when they are unavailable.

A local agency in London

Same timezone and a face to meet, which genuinely matters for some teams. You are also paying London market for SaaS, fintech, and AI product talent. rates for the whole team including the layers that never touch your full stack development, and a local shortlist is a small shortlist.

Arcode

A small senior team. The people who scope the full stack development write the code, you get weekly demos instead of status decks, and the engagement ends when the thing is live and handed over.

Working with teams in London

London market for SaaS, fintech, and AI product talent. We work with clients in London remotely and keep overlapping hours in GMT/BST. We usually collaborate in English.

How we work with London teams

London is on GMT/BST, which gives us an overlapping working day rather than a handful of shared hours. Standups, reviews, and demos all fit in normal business hours for both sides.

What London clients usually need

London work is heavily SaaS and fintech: dashboards over real financial data, onboarding and KYC flows, and increasingly LLM features layered onto products that already have paying users.

Contracts, data, and compliance

Procurement in London tends to ask for a DPA, evidence of where data sits, and a security questionnaire before signing. We handle those upfront, and we keep personal data in UK or EU regions by default.
