AI systems that ship in production
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.
Discovery stays short and specific: users, data, and risks. After that we build the critical path first and strengthen it from there.
We work best with startups and product teams hiring AI engineering talent who want a partner that ships. Agents, MCP servers, RAG pipelines, and LLM features wired into real software rather than demos.
What you get
- Production AI agents with tool calling
- MCP servers connected to your stack
- RAG over company knowledge
- OpenAI and Claude product integrations
- One studio accountable for the result
- Design and engineering on the same schedule
- Support available after launch
How engagement works
As your AI 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. Nothing here waits on a handover between separate teams.
- 02
Design
System design, AI/tool boundaries, interface direction, and interaction prototypes. On AI engineering projects we favour practical architecture over trendy defaults.
- 03
Build
Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. The work for teams in France stays tied to the outcome you asked for.
- 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 AI engineer work these are the defaults, and the reason each one is on the list.
- OpenAI
- a second model provider, so a single vendor's outage or price change is not your problem
- Claude
- long-context reasoning and reliable tool calling for agent work
- MCP
- the Model Context Protocol, so your tools plug into Claude, Cursor, and other agent clients without a custom adapter for each
- LangChain
- orchestration for multi-step chains when the flow is genuinely complex
- 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
What the first weeks look like
- Days 1-3
Context and constraints
Codebase, deploy path, and what "done" means for the AI engineering. Short, because the useful version of this is specific.
- Week 1
First shipped slice
Something real goes out in the first week — production ai agents with tool calling 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 AI 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 AI engineering, and a local shortlist is a small shortlist.
Arcode
A small senior team. The people who scope the AI 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.
