Your team ships code.
But are you shipping the right product?
I'm a product engineer who embeds with your team to bridge the gap between what your product needs and what your engineering makes possible.
Trusted by teams at IBM 🇺🇸, Batelco 🇧🇭 (🇪🇬 🇸🇬), an EU-funded digital modernization program 🇨🇿 (🇸🇰 🇭🇺 🇵🇱), Algeco-Scotsman 🇷🇺 🇺🇦, Amadeus 🇫🇷, BNP PARIBAS 🇫🇷, and other companies whose names won’t impress you at parties.
Shipped products to 100M+ people.
Sound familiar?
You've got talented engineers. But something isn't clicking.
You ship features but users don't feel the difference
Your team delivers on time, PRs get merged, sprints get completed — but users aren't more engaged, retention is flat, and nobody can point to last quarter's work and say "that mattered." You're measuring output, not impact.
Engineering and product speak different languages
Product writes specs. Engineering builds exactly what's asked. Nobody is happy. The gap between what product wants and what engineering knows is possible never gets bridged.
The codebase is a liability
Nobody wants to touch that module. Onboarding new developers takes months. The original architect left, and the technical debt is compounding faster than your runway.
AI hype, zero gains
Leadership wants "AI in the workflow." Your team tried Copilot, produced slop code that had to be trashed after months. Nobody knows how to integrate AI tools in a way that actually multiplies output without sacrificing quality.
I help you figure out which features should exist
— and I enable your team to build them.
What I do
I don’t write reports.
(Okay, sometimes I do — someone has to keep management happy.)
I embed with your team, ship code, and own outcomes.
I also ship the boring stuff nobody has time for.
Full-Stack Product Prototyping
You have a product concept that needs to become real. I build the prototype — frontend, backend, database, deployment — with production-quality code that doesn't need to be thrown away.
Product-Engineering Assessment
A 3-week deep dive — one week with product, one week with engineering, one week to bridge the gap. Then I take a week off because even I need to process that much organizational dysfunction. You get a written assessment with a prioritized action plan — and I stick around to make sure it actually gets executed.
Embedded Product Engineering
I join your team as a hands-on product engineer. I write code, but I also ask "why are we building this?" and "how will we know it worked?" Finding the 20% effort that delivers 80% of the value.
AI Developer Workflow Integration
Your agents mass-produce code. Your humans write elegant code. I bridge the two — because the future isn't AI or human, it's AI-generated code that meets human standards of elegance. I set up the workflows, reviews, and guardrails so your team ships faster without drowning in slop.
How it works
Start small. See results. Then decide.
We talk
Book a free 30-min call. Tell me what's going on. I'll tell you honestly if I can help.
I dig in
I review your product-engineering alignment, or I start shipping code in week one. No ramp-up theater.
You get outcomes
A written assessment with actionable priorities. Or merged PRs that move your product forward. Tangible results, not slide decks.
Who I am
25+ years building, leading, and shipping software. CTO, tech lead, best-selling book author, university teacher, and researcher at one of France's top AI labs. EPITA Engineer + MSci in Cognitive Science.
I think in products, not features. I write code every day.
More about meBy the numbers
Not just lines of code — hundreds of production PRs shipped, reviewed, and merged. Volume and quality, from week one to the last day of the engagement.
Products I’ve helped build and ship serve over 100 million people worldwide — from telecom platforms to enterprise SaaS.
Streamlined review and deployment processes, cutting merge cycles from two weeks to two days. Faster feedback loops, faster value delivery.
