You need to ship, not to hire
A senior engineer takes months to recruit. Your product needs to exist now, not after a hiring cycle.
AI PRODUCT ENGINEERING & AUTOMATION
Ship your AI product in weeks, not quarters.
I'm a senior engineer who designs and builds custom AI products end to end - from MVP to production. Need to automate your operations instead of build? I do that too. Either way, you work with me directly, not an agency.

Agencies are slow and detached
Dev shops quote in quarters, spread you across juniors, and hand back code no one on your side can maintain.
AI bolted on as an afterthought
Adding AI late means costly rebuilds. Your product should be architected with AI from day one, by someone who has done it.
How it works
01
Scope what matters
We pin down the smallest version worth shipping and the fastest safe path to it. Clear scope, clear priorities, no scope creep.
02
Build it for real
I design and build the whole thing - product, AI, and infrastructure - and you see working software every week, not just slides.
03
Ship and support
It goes live on your cloud, production-ready. I stay on to iterate, harden, and support it - no handoff to a stranger.
The engineer
You work directly with the engineer
No account managers. No handoffs. Every project gets my full attention, from first call to production.
I've spent 18 years building software that has to work: nationwide MedTech platforms, real-time trading systems, and AI-powered products. Today I bring that engineering depth to growing businesses - building the products they need and automating the work that slows them down. From first call to production, you work with me directly.

A franchise-ready booking platform for a cat hotel, built solo in 4 months
A cat hotel near Annecy couldn't find anyone to build the reservation platform it needed to franchise, and agencies were out of budget. Here is how I built it solo: public booking wizard, multi-hotel back-office, and lean infrastructure.

In their words
What people I've built with say
Recommendations from engineers, managers and colleagues I've worked with, on LinkedIn.
One of the best teammates I have ever had. We developed the m3-test booking and tracking platform together from scratch. Olivier was super quick to design the data model and the user interface. He is an invaluable asset in turning your ideas into production software.
Jonathan Weibel
Senior Software Engineer · worked with me on m3-test
Self-motivated and wise software engineer with huge knowledge. If you ever need someone to deliver under pressure, no slip-ups, just results, Olivier is your man!
Frédéric Musso
Product & Design @ Finary
