Senior full-stack product engineering
Splitting work across several freelancers creates handoff problems. Keeping it with one accountable engineer or small pod protects both quality and pace.
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 companies hiring a proven software engineer. End-to-end ownership across React/Next.js, NestJS, databases, and cloud.
What you get
- Scalable web applications
- Clean architecture and APIs
- Performance and accessibility
- Remote-ready collaboration
- One studio accountable for the result
- Design and engineering on the same schedule
- Support available after launch
How engagement works
As your software engineer, 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. On software engineering projects we favour practical architecture over trendy defaults.
- 02
Design
System design, AI/tool boundaries, interface direction, and interaction prototypes. The work for teams in France stays tied to the outcome you asked for.
- 03
Build
Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. You see progress on the critical path every week.
- 04
Launch
Ship, monitor, harden, and keep improving models, tools, and product after go-live. Nothing here waits on a handover between separate teams.
How we build it, and why
The stack is chosen per project, not applied from a template. For software engineer work these are the defaults, and the reason each one is on the list.
- TypeScript
- types across the whole stack, which catches the class of bug that only shows up in production
- Next.js
- server rendering and static generation in one framework, so marketing pages stay fast and app routes stay dynamic
- NestJS
- structure and dependency injection on the backend, which keeps a growing API from turning into a pile of route handlers
- PostgreSQL
- relational integrity for data you cannot afford to get wrong
- AWS
- the services you grow into, once a managed platform stops being enough
What the first weeks look like
- Days 1-3
Context and constraints
Codebase, deploy path, and what "done" means for the software engineering. Short, because the useful version of this is specific.
- Week 1
First shipped slice
Something real goes out in the first week — scalable web applications 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 software engineering 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 France
Same timezone and a face to meet, which genuinely matters for some teams. You are also paying French brands seeking polished product UX with strong engineering. rates for the whole team including the layers that never touch your software engineering, and a local shortlist is a small shortlist.
Arcode
A small senior team. The people who scope the software engineering 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 France
French brands seeking polished product UX with strong engineering. Work is remote-first (CET/CEST), with written updates you can read in your own time. We usually collaborate in French/English.
How we work with France teams
France is three to four hours behind us, so the afternoon is shared in full. Work is delivered in English; French-language briefs are fine to send, and documentation and updates come back in English unless you need otherwise.
What France clients usually need
French briefs often pair a strong brand with an ageing site — a marketing-led rebuild where the design matters as much as the stack underneath it. Marketplace and subscription products are the other recurring theme.
Contracts, data, and compliance
GDPR and CNIL guidance drive the data decisions, so consent handling and analytics get scoped properly instead of being dropped in as a cookie banner at the end. We invoice in EUR with reverse-charge VAT for registered businesses.
