About Mehdi

Most AI consultants advise. I build and operate what I build.
🔬 medicum.fr: designed from scratch, alone. Medical RAG, 450,000 health professionals indexed, 200,000 sessions/month, €0 ads. White page to production in 6 months.
🏠 realestateai.ae: AI real estate search, text-to-image, in real-time.

When I recommend an architecture or a stack, it's because I'm running it myself. Whether you're starting from scratch or already have a system that's not delivering, I know both situations from the inside.

📊 Client results:
  • +388% users in 12 months for a legaltech
  • RAG accuracy from 26% to 98%, latency divided by 3.5
  • Functional POCs delivered in 2 to 4 weeks
  • €100K+ in research grants unlocked
  • 32 systems deployed in production
🛠️ Scope: LLM, RAG, AI agents, Computer Vision, GenAI (photos, videos, documents...), end-to-end infrastructure: training, evaluation, deployment, monitoring.

💼 How I work:
  • 🏗️ Project: POC, MVP, go-live. Defined scope, defined deliverable. The most frequent format.
  • 🔍 AI Audit: 2 weeks, roadmap + POC.
  • ⟳ Monthly support: weekly sprints, dedicated senior, 24h response time.

A clear, measured, and serious approach to work, in my opinion. No exorbitant quotes, but a deliberately limited preliminary work proposal that allows for an initial assessment. No unfounded promises, but much appreciated scientific honesty.
