Description

🚀 Full-Stack & SaaS Designer — React / TypeScript / Supabase

I design and develop modern web applications with a product and business-oriented approach.

Unlike a traditional developer, I have launched several SaaS products myself (Aciersenligne, RelanceAuto), which allows me to understand your real challenges: acquisition, performance, UX, automation, and scalability.

🤖 AI-Augmented Approach

I work daily with AI tools to accelerate development, ensure code reliability, and improve the overall quality of deliverables.

I am also training in creating AI agents and intelligent workflows to automate business tasks and save teams time.

💻 My Expertise:

• Front-end: React, Next.js, TypeScript, TailwindCSS

• Back-end: Supabase, Node.js, REST APIs, PostgreSQL

• SaaS Architecture: subscriptions, payments, dashboards, automations

• AI & Automation: agents, integrations, intelligent workflows

🎯 What I Bring Concretely:

• Transform an idea into a functional product quickly

• Optimize an existing application (UX, structure, performance)

• Build reliable, scalable, and maintainable SaaS solutions

• A product vision from the field, not just technical

⚡ My Difference:

I don't just code features — I build solutions designed to be used, sold, and to grow your business, leveraging AI to go faster and further.

Available for remote or hybrid missions.
