Frontend to backend, one owner
A job description rarely describes the real risk in a product. It helps to work with someone who has already built something similar.
Discovery stays short and specific: users, data, and risks. After that we build the critical path first and strengthen it from there.
Most people who reach this page are founders and teams needing full-stack ownership. 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.
- 01
Discover
Goals, constraints, data sources, and success metrics, all settled before we touch architecture or prompts. You see progress on the critical path every week.
- 02
Design
System design, AI/tool boundaries, interface direction, and interaction prototypes. Nothing here waits on a handover between separate teams.
- 03
Build
Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. On full stack development projects we favour practical architecture over trendy defaults.
- 04
Launch
Ship, monitor, harden, and keep improving models, tools, and product after go-live. The work for teams in Paris stays tied to the outcome you asked for.
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
- 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.
- Week 1
First shipped slice
Something real goes out in the first week — complete product delivery rather than a setup ticket.
- 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.
- 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 Paris
Same timezone and a face to meet, which genuinely matters for some teams. You are also paying Paris startups and brands seeking distinctive digital products. 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 Paris
Paris startups and brands seeking distinctive digital products. We work with clients in Paris remotely and keep overlapping hours in CET/CEST. We usually collaborate in French/English.
How we work with Paris teams
Paris is three to four hours behind us, so the whole afternoon is shared. We work in English; French-language briefs are fine to send, and the deliverables come back in English.
What Paris clients usually need
Paris work is often brand-led: a company with strong design standards that needs the engineering to match. Marketplaces, subscription products, and content platforms recur.
Contracts, data, and compliance
GDPR and CNIL expectations shape analytics and consent from the start. We invoice in EUR, with reverse-charge VAT for registered businesses, and default to EU-hosted data.
