About Daniel

AI-powered Tech PO/PM service. Costs ÷4, go to market ×10.
I bring my 20 years of experience and large company processes for "enterprise-grade" applications.

I am a Tech Lead and Product Engineer with 20 years of experience. Thanks to an AI-augmented development system of my own design, Sandwich, I replace a team of 4-5 people: architecture, specs, backend, frontend, tests, documentation, deployment.

You keep a designer on the side. That's all.

WHY IT'S DIFFERENT FROM "VIBE CODING"
Vibe coding is fast but produces disposable code. My approach maintains velocity (×10) and savings (÷4) while applying large company development standards: specs driven, TDD, automated tests, E2E tests, structured sprints.

I deliver a production-ready application that is scalable and auditable in the long term.

RECENT RESULTS
- B2B2C module for L'Oréal (used by 100+ brands, millions of users/month).
- Full multi-tenant back office and Admin delivered in 5 weeks — squad equivalent: 5 months
- Stripe account synchronization SaaS (subscriptions, webhooks, magic links) in 2.5 weeks — equivalent: 3 months
- PtiDonjon: Complete redesign + DB migration in production in 27 days — equivalent: 3 months

FOR WHOM
- You haven't yet integrated AI into your development and want to see what it concretely changes
- You have a new product to launch without building a dedicated team
- You have tried vibe coding and are looking for something more solid

I INTERVENE AS
→ Tech PO Proxy for an existing product
→ Senior full-stack Tech Lead for a small team
→ Outsourced CTO for a new product
→ Senior reinforcement to unblock a roadmap
