# Startup MVP Builder • Fractional CTO • I help companies go from idea to product in a few weeks
I design and launch digital products quickly.
After more than 15 years in corporate development and projects that generated several tens of millions in revenue, I am now focused on one thing:
👉 transforming an idea into a functional product, ready for exploitation
🎯 What I do
I intervene upstream and in execution to:
• frame a product
• identify business levers
• design a suitable architecture
• develop a robust MVP
• accelerate time to market
Goal: reduce the time between the idea and the first results
I intervene as:
• builder (I build fast and well)
• operator (I understand business challenges)
• accelerator (I remove technical friction)
🚀 Concrete cases
• process automation: 3h → 10 seconds
• solutions generating several million euros in revenue
• products launched from 0 to 1 in a few weeks
🛠️ Areas of intervention
• MVP / rapid prototyping
• automation & optimization
• high ROI internal tools
• SaaS products
• redesign and acceleration of existing products
⚙️ Stack & environment
TypeScript • Next.js • React
Cloud (AWS, GCP, Azure)
Payment (Stripe, Mangopay, Lemonway)
CI/CD • Monitoring • Scalable architecture
💰 Collaboration model
I work exclusively on deliverables, not on time spent.
👉 each mission is defined around a clear objective: a functional, usable product ready to generate value.
⏱️ Intervention framework
I prefer fixed-price work over daily rates for endless periods.
👉 objective: move fast, deliver, and create concrete impact without getting bogged down in long projects
I am ready for concrete projects with real potential and rapid execution.
