Cross-platform mobile from one studio
Slides do not launch products. Design, engineering, and launch need to sit with the same team on the same schedule.
We bring product thinking and engineering together, so structure, UI, APIs, and the launch checklist live in one plan.
We work best with brands searching for a React Native agency who want a partner that ships. React Native and Expo app development with production backends, payments, and store-ready delivery.
What you get
- iOS and Android apps
- Expo and native modules
- API and auth systems
- Store launch support
- One studio accountable for the result
- Design and engineering on the same schedule
- Support available after launch
How engagement works
As your React Native agency, 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 React Native app development 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 Paris 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 React Native agency work these are the defaults, and the reason each one is on the list.
- React Native
- one codebase for iOS and Android, which halves the surface area you maintain after launch
- Expo
- over-the-air updates and managed builds, so shipping a fix does not mean waiting on app store review
- TypeScript
- types across the whole stack, which catches the class of bug that only shows up in production
- Firebase
- auth, push, and realtime sync without standing up your own infrastructure first
- NestJS
- structure and dependency injection on the backend, which keeps a growing API from turning into a pile of route handlers
What the first weeks look like
- Week 1
Scope and architecture
Users, data, integrations, and constraints, ending in a written plan for the React Native app development that you approve before anyone opens an editor.
- Weeks 2-3
Design the critical path
The screens that carry the product, prototyped and clickable. Design and engineering review together, so nothing gets drawn that cannot ship.
- Weeks 4-8
Build in weekly slices
Every week ends with something on a real URL. ios and android apps lands early, because the rest of the plan depends on it working.
- Launch
Ship, measure, hand over
Release, monitoring, analytics, and a documented handover, so your team can carry it without calling us.
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 React Native app 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 React Native app development, and a local shortlist is a small shortlist.
Arcode
A small senior team. The people who scope the React Native app 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.
