About Amoin Clémentine

Senior Full-Stack Developer | React & Node.js Expert | 8 years of experience
Code is good. A product that runs and generates revenue is better.

After 8 years navigating the web ecosystem, particularly within tech agencies like ELEPHANT technologies, I've learned one essential thing: technology is just a tool to serve your business. My role is to ensure this tool is as solid, scalable, and performant as possible.
What I bring to your projects:

A 360° vision: I don't just "push tickets." I design robust backend architectures (Node.js/PostgreSQL) and fluid frontend interfaces (React/Next.js) always thinking about the end-user.

The "Clean Code" culture: I develop with TypeScript to guarantee the stability of your applications. Clean code today means thousands of euros saved in maintenance tomorrow.

Autonomy & DevOps: Docker, CI/CD, AWS... I deliver "turnkey" solutions. You don't need to manage servers, I'll take care of it.

Team spirit: Accustomed to Agile methods, I enjoy communicating, explaining my technical choices, and collaborating closely with product and design teams.

My preferred stack: 🚀 Front: React.js, Next.js, TypeScript, Tailwind. ⚙️ Back: Node.js (NestJS/Express), REST/GraphQL API. 📦 Ops: Docker, GitHub Actions, AWS.

My goal is simple: to transform your complex ideas into a simple and effective technical reality.
