Johan Elberg

I develop AI-augmented applications that run in production, not demos, not dusty POCs.

My specialty: I'm both an AI Engineer and a full-stack developer. When you entrust me with a project, you get the AI agent AND the surrounding application. A single freelancer, a complete product.

I handle the entire chain: design of autonomous AI agents, orchestration of agentic workflows, automation via LLM (Claude, GPT, open-source models) using MCP, RAG, and prompt engineering. On the product side: development of cross-platform mobile applications (React Native, Expo, TypeScript), creation of SaaS and web applications (Next.js, Nuxt, React, Vue.js), and setup of custom backends. I choose the most suitable stack for your context (Node.js, Fastify, PostgreSQL, Supabase, Strapi, Docker) based on your technical and business constraints.

Concrete examples: complete development (mobile app, admin back-office, backend) of a live shopping platform enabling sellers to stream live and spectators to buy in real-time. Design of an AI agent system for large-scale, expert SEO content generation and automated publication via CMS.

10 years of experience in full-stack development and AI integration. I work with clients in France and internationally, in French or English.
