Automate the tasks that slow your business down.
I automate your processes, connect the tools you already use and build the custom software you need: internal tools, CRMs, dashboards, client portals.

Nothing goes out without your OK.
Do these situations ring a bell?
One by one, they are small tasks. Added up, they take a big part of the week and slow the whole team down.
- Integration
You copy the same information into several pieces of software.
- Automation
Client requests come in by email, phone and web form, and some get lost.
- Custom software
An Excel file has become the company’s central tool, and it is reaching its limits.
- Automation
Following up on quotes and invoices depends on everyone’s memory.
- Automation
Every week, someone compiles the figures by hand to take stock.
- Custom software
Off-the-shelf software doesn’t fit the way you work.
Three ways to simplify how you work
Each offer can be a project on its own. They combine when it makes sense, with one point of contact from start to finish.
Automation & AI

- The CRM is updatedThe client is found or created, and the request joins their history.

Indicative list. The brands mentioned belong to their owners and imply no partnership.
n8n, an open foundation
I mainly use n8n, an open-source automation platform. Your automations stay readable and easy to change.
Your data under control
n8n can be hosted in Europe or Switzerland to meet your GDPR or Swiss FADP requirements.
Code when it’s needed
No connector available? I build the integration directly on the software’s API.
What working together looks like
A simple framework, so you always know where your project stands.
Discovery call
30 minutes by video. You describe how you work, and I tell you honestly whether I can help.
Scoping and proposal
I analyse your processes and send you a written proposal: scope, timeline and price.
Step-by-step delivery
Regular demos: you see the result take shape and keep control of the priorities.
Go-live and support
Training, documentation, then maintenance and improvements if you wish.
A price you know before we start
Each project is quoted after scoping. These figures give you a rough idea.

A developer, not an agency
I’m Cantin Bartel, a full-stack developer since 2021. After working at a French startup, I went independent to build custom web applications for small and mid-sized businesses: internal tools, CRMs, booking platforms.
Today I add automation and AI, so your tools work together.

One point of contact
You talk directly to the person who designs and builds your solution.
Explanations without jargon
Every technical choice is explained simply, with what it means for you.
A solution you own
Code, access and documentation are handed over to you. You stay free.
Before you get started
I’m not technical. Is that a problem?
Not at all. You know your business, I handle the technical side. I explain every choice simply, and the tools I deliver are designed to be used without any technical skills.
Will AI make decisions for me?
No. AI is used to read, sort, summarise and prepare. Important actions, such as sending an email to a client, still require your approval.
Where is my data hosted?
We decide together during scoping: on your servers, with a European host or in Switzerland. n8n can be self-hosted, so your data doesn’t have to go through a third-party service.
What happens if one of my tools changes?
Automations are documented and monitored. If a tool changes, I update them, under a maintenance contract or on request.
Do you work with companies outside France?
Yes. Everything happens by video call and email. Quotes can be issued in euros or Swiss francs.
How much does a project cost?
It depends on the scope. After the discovery call, I send you a written, priced proposal. Price guidelines are shown above.
