Founder of SYNN-IA — I design digital products, automations and AI-assisted tools that solve real business problems, from the idea to production.
📍 Dijon, France · 🎓 Bachelor in Management @ BSB · 🌐 nathanfernandes.fr
- Full-stack web development — React, Next.js, TypeScript, Supabase
- Process automation & AI integration — Claude, GPT and related models, always with human validation
- Product design — from need analysis to prototype, then to production
My approach: start from the business problem, then choose the technology.
