I build AI products and automations that hold up in production.
Freelance product engineer. I take founders and SMBs from audit to custom system: automated workflows, internal tools, SaaS building blocks. Reliable, documented, and yours.
Your team's time is going to the wrong places.
If any of these habits sound familiar, a process is waiting to be automated.
And the more you grow, the more these tasks pile up: at some point you're hiring just to keep up. Automation lifts that ceiling.
Manual data entry
Your teams re-type by hand data that already exists somewhere else.
Re-keying between tools
The same information moves from one app to another, copied and pasted.
Scattered data
Files, emails, spreadsheets: information lives everywhere, the truth nowhere.
Reporting done by hand
Every report is rebuilt manually, at the cost of hours lost.
Processes that run without you.
How I work as a freelancer, from analysis to a system running in production. No jargon, no over-engineering.
Process audit
I map your real workflows and spot the tasks truly worth automating: the ones that cost time and create errors.
Workflow architecture
I design clear, documented and maintainable flows. You understand what happens at every step, and you stay in control.
Automation & integrations
Your tools finally talk to each other. Data flows without intervention, from source to reporting, via n8n, Make, Zapier, Airtable and Notion.
Custom tooling
When no-code hits its limits, I build the tool you need: web platform, internal tool, SaaS building block.
Not on the list? I adapt to your tools: I work with your existing stack instead of forcing a new one on you.
Concrete results, with real clients.
Problem, solution, result. Scroll through. Each case has its own page.
In the press
Freelance product engineer. I build systems that last over time.
Hi, I'm Corentin de Maupeou. I've been coding since I was 11: the web at 14, blockchain at 16, then full SaaS products built end to end. I've shipped my own tools, worked with startups, and spent the last few years in the entrepreneurial ecosystem - startups, incubators (including HEC Paris), SMBs - from Paris.
Along the way I kept seeing the same thing: strong teams losing hours on tasks no one should be doing by hand. That's where STRATUS, my studio, comes from. I automate those processes: no-code / low-code when that's enough, custom-built when it's not. I also speak at conferences on AI, automation and innovation in business.
My approach comes down to three words: pragmatism, reliability, measurable impact. No over-engineering, no jargon. Simple systems that work, that you understand, and that you keep.
Let's book 30 minutes.
A call to identify what can be automated at your company. Concrete, no commitment.
