A product that runs.Without hiring a team.
I'm Julien: shipping software since 2010. As a CTO, I built a full tech team from scratch, before the AI era. Today, AI replaces the team. It doesn't replace the person accountable.
Who answers when your software breaks at rush hour?
Code got cheap.
Accountability did not.
Every year the machines write more of the code, and the build stops being the hard part. What is left is the part nobody puts on an invoice: the error caught before your customer sees it, the dependency updated before it rots, the migration planned instead of survived. None of that is a process you can buy. It is a person who knows your product line by line and puts their name on it.
So that is what the agency is. Not capacity, not a pod of juniors behind an account manager: one senior engineer with an AI-native delivery system, a client list capped on purpose because nobody knows that many products line by line, month to month so the only thing keeping you is the work itself. If you want someone who builds and then disappears, the market is full of doors. If you want someone who stays and answers, there is one.
The same product.
A different week.
- Something breaks while you are in a meeting. It stays broken until the meeting ends.
- You find out the app is down the way you always do: a customer tells you.
- A client reports a bug you did not know was possible, and nobody can say how long it had been there.
- Every technical question lands on your desk, and you are never quite sure the answer you give is the honest one.
- The features that would actually move the business keep waiting, because the urgent thing always wins.
- It breaks at 14:12. It is caught, diagnosed and fixed while you are still in the room.
- One page tells you what is live, what is running, and what is waiting on you.
- Errors reach me the second they fire, so most of them are gone before anyone could report them.
- Technical questions have one owner, and the answer comes back with the trade-off spelled out.
- Your head is free for the product, because the urgent thing already belongs to someone else.
The real cost of no one being accountable.
What I have watched happen, more than once.
Your clients are your QA.
Nobody is watching, so the people paying you are the ones finding the bugs. Every report is a small withdrawal from the trust account, and you never get to see the balance.
You run the business and the servers.
Two jobs, one head. The technical one never gives notice and always lands at the worst hour. Burnout is not dramatic; it is just how Sunday evening starts to feel.
The product grows like a sidebar.
Every request becomes one more entry in the menu, because adding is easier than deciding. A year in, nobody can say what the product actually is, and the sidebar is the only map.
AI makes everything faster. Including the drive into the wall.
Three ways to work with me.
Expert Audit
You connect the repository, I read the code: all of it. Within 48 hours you get a written verdict and a debrief: what is solid, what breaks next, what to fix first, and what I would do if it were mine.
La Résidence
Your product moves in: watched around the clock, fixed before you notice, evolving every month. You run the business; I answer for the tech, including at 3am. Month to month, no lock-in.
Your internal AI system
One system, built into how your company already works. Not a chatbot parked on top of your data: agents that carry real work, wired to your tools, documented and yours at the end of it.

I built the team. Then the rules changed.
Fintech in Luxembourg, then co-founder and CTO of kodehyve: sole developer to a team of twenty, and a decade of being the one who gets woken up when production breaks. Then the models got good enough that a department's worth of code stopped being the bottleneck, and the only scarce thing left was judgment and the willingness to answer for it. So I stopped hiring and built the delivery system instead. ITzWorking is what came out.
- 10+ yrsshipping in production
- CTOkodehyve, sole dev to 20+
- ~90%of the agency runs on Nexus, ITzWorking's OS
Do you know what your software needs next?
Four questions place your software on the nine stages, and you leave with a plan built for where you actually are: what to focus on now, what is too early, and what would burn time and money if you started it today. Free.
