For CTOs, founders & product leads
A .NET / GenAI subject blocked? I unblock it in 10 days.
A module to ship, an AI integration, an architecture that's stuck, a performance issue that won't hold: I step in as a freelancer, from scoping to production. Code in your repo, tests, docs, handover — and public products online so you can judge for yourself before you sign.

How we work together.
Four steps, zero surprises. At each step you receive a concrete artifact — not a promise.
- Step 1
Discovery call — 30 min, free
You describe the subject, I ask the uncomfortable questions. If I'm not the right profile, I tell you straight away — and point you elsewhere if I can.
→ Honest go / no-go
- Step 2
Written proposal within 48 h
Frozen scope, written success criteria, fixed price (sprint) or day rate (mission). No fuzzy line: you know exactly what's delivered, when, and for how much.
→ Fixed-scope, fixed-price quote
- Step 3
Execution with daily visibility
A written async progress note every day (5 lines), a mid-point demo. You watch the work advance in your repo — no three-week tunnel.
→ Daily async + mid-sprint demo
- Step 4
Delivery and handover
Code in your repo (merged PR), tests, architecture doc, a handover session with your team. No dependency on my presence afterwards.
→ Code + tests + doc + handover
Judge for yourself: 4 products online.
Not mockups — deployed products, open to the public. Click, test, form your own opinion before the first call.
The questions I get before signing.
- How quickly can you start?
- A sprint can start the week of scoping. A longer mission starts within a week of the proposal being accepted.
- Who owns the code?
- You do, entirely. Everything is delivered in your repo (merged PR), with tests and an architecture doc. No dependency on my presence after handover.
- How does billing work?
- Sprint: fixed price, 50% at kick-off, 50% at delivery. Longer mission: day rate billed monthly. A written quote with frozen scope in both cases — no surprise overruns.
- Contract, NDA, legal framework?
- Independent developer registered in France. A service contract and NDA are signed before any access to your code — your templates or mine.
- Remote or on-site?
- Remote across France and Europe, with written daily async check-ins. Hybrid possible in the Montpellier / Nîmes area, occasional travel for a kick-off.
Shall we look at your subject together?
30 minutes, free, no commitment. If I'm not the right profile, I tell you — and point you elsewhere if I can.
