About Alexandre

Full Stack & AI Developer - React / Next.js / Flutter / Node.js

Hi! I'm Alex, a Full Stack developer with 6 years of experience, based in Lyon.
I develop web and mobile apps from scratch, and I integrate agentic AI into my projects and those of my clients. Not just "plugging in a chatbot": I design AI agent systems that automate concrete tasks and integrate into existing products.

On a daily basis:
→ Mobile apps (Flutter, React Native)
→ Web platforms (React, Next.js)
→ Backend and APIs (Node.js, TypeScript, MongoDB)
→ Agentic AI: agent orchestration, LLM integration, MCP
→ Production deployment, CI/CD, Docker
Recent freelance projects (full autonomy, from design to deployment):
→ MateApp: Flutter social app + Next.js back-office
→ Keepture: React Native photo app + Node.js backend
→ Acqua Protection: Next.js management platform + pro mobile app
→ Boost for Letterboxd: open-source Chrome extension
-> EazyDiet: Flutter nutrition and diet app, fully offline

What I can bring:
→ Develop your web or mobile app
→ Integrate AI into an existing product
→ Train your team on agentic AI practices

Before freelancing: 4 years at Nicecactus (Sophia Antipolis), Full Stack developer and Project Manager on an Esport platform, team of 10 developers. Before that, a life in Esport (player, organizer) that taught me to communicate, adapt, and keep a cool head.
Available in Lyon, hybrid or full remote.
