A fractional tech lead for products built with AI
A senior fullstack engineer on your project, 1 to 5 days a week depending on your needs, for as long as you need. 12 years shipping products, founding engineer twice. You keep moving fast with AI; I make sure what you build holds.
Who it is for
- Founders and small business owners, a bit technical, who vibe-coded a product and now see the limits: bugs nobody understands, first paying customers, security questions.
- Small dev teams adopting Claude Code, Codex or other coding agents, who want the speed without losing control of the codebase.
- Companies whose software supports the business and that need a real senior on it, whatever the rhythm.
How it works
1. The reset
One or two weeks to understand the project before touching it: the business, the code, the architecture, security, the pipeline. Then the foundations: a harness around the AI agents, guidelines, a clean CI/CD. You get a full written report within two weeks. Why I start without writing code
2. The follow-up
For the life of the project, at the rhythm it needs: from 1 to 5 days a week, depending on your needs. Code reviews, architecture decisions, leading the devs, security and performance checks, debugging the incomprehensible, and the AI watch so you do not spend your evenings on it. The part-time senior developer
Only want the diagnosis? The reset also works on its own, as an audit with its full written report.
Questions
Fractional tech lead or fractional CTO?
Same idea: a senior on your project over months, for the days you need. I say tech lead because I stay hands-on: architecture, reviews, harnesses, and features when needed, not only strategy.
Do I have to stop vibe-coding?
No. The goal is that you can keep going with AI safely: a harness that catches mistakes, clear guidelines, a pipeline that refuses what breaks.
Can you work with my developers or my agency?
Yes. Leading developers and reviewing their code is part of the job, whether they are employees, freelancers or an agency.
Do you work remotely?
Mostly, with on-site days when the project calls for them, such as a kickoff or a workshop. In English or French.
How much does it cost?
It depends on the rhythm and the project. Tell me about yours and I will come back with a proposal.
Tell me about your project
A few lines are enough: what the product does, who works on it, where it hurts. By email or on LinkedIn, whichever you prefer.
