Back to original languageAbout Etienne
Faced with the LLM revolution, value lies in embedded intelligence, interconnectivity, and automation.
As anAI Product Engineer(with aPhD in Physicson complex data systems), I deploy AI-augmented digital solutions. I combine data architecture, AI-assisted development mastery (Cursor, Claude Code), and technical agility to transform your MVPs or processes into high-performance platforms.
My Areas of Expertise:
- **AI & LLM**: Integration (Claude, GPT, Gemini), RAG architectures (Python) to leverage your internal data
- **Web & Mobile**: Stack adapted to your needs: Next.js / Node.js (scalable infrastructure), Flutter (mobile optimization), Supabase (robust data) or Bubble.io (agile needs).
- **Automation (n8n, APIs)**: Data pipelines and tool interconnection to eliminate time-consuming tasks.
Why work together?
- **Velocity (Vibe Coding)**: Via Cursor, I reduce build cycles: what took months now takes weeks, while maintaining project control.
- **Rigor (PhD)**: I bring true algorithmic rigor to your data architectures.
- **Iterative Approach**: Short sprints (Scoping ➔ Prototype ➔ Deployment).
Let's discuss your goals to define the ideal architecture!
