About Jules-Camille

Hello, I'm Jules-Camille.

I'm not just a Fullstack developer: I'm an AI Product Engineer. I help companies reliably, securely, and profitably integrate Artificial Intelligence into their business applications.

Formerly a Product Designer and Tech Lead within the B2B SaaS ecosystem (ex-Ubiwan / Coyote Group), I bridge the gap between your strategic challenges (ROI, User Experience) and technical realities (AI Architecture, Scalability).

🚀 MY EXPERTISE: AI & DATA ARCHITECTURE
No more hallucinating "ChatGPT demos." I build robust systems based on your own data:

RAG (Retrieval-Augmented Generation) Engines: Creation of intelligent and verified knowledge bases.

Vector Databases: Mastery of Pinecone and Qdrant for ultra-fast semantic search.

LLM Integration: OpenAI API, Anthropic, Mistral.

💻 MY TECHNICAL STACK (PERFORMANCE & SECURITY)

Back-End (Robust): NestJS, Node.js, scalable microservices or monolithic architectures.

Front-End (Ultra-Fast): Next.js (SSR/SSG), React, TypeScript, Tailwind CSS.

Modern Data: PostgreSQL, Convex, Supabase.

🎯 MY TYPICAL INTERVENTION OFFERS:

The AI Sprint (10 days): Transformation of your inert database into a functional AI assistant prototype (RAG).

Architecture & Build: Development of your B2B SaaS or platform from A to Z with Next.js & NestJS.

Audit & Consulting: How to prepare your internal data to make it usable by AI without confidentiality leaks.

📍 Available in Paris & Remotely. Ready to audit your technical needs within the day.
