About Badreddine

I develop modern web applications (SaaS, dashboards, web platforms, and high-performance websites) in React.js and Next.js, with a focus on performance, structure, and user experience.

I support projects from conception to deployment, with a product-oriented approach: clarity, speed of execution, and maintainable code.

My experience

👨‍💻 Experience built through several internships and numerous concrete personal projects:

Complete web applications (front + back)
SaaS projects and dashboard/management tools
Optimized websites and landing pages for performance + SEO
Structured Node.js APIs and backends
Experimentation with modern architectures (Next.js, fullstack JS)
What I offer

Modern and fluid interfaces with React.js & Next.js
Backend development with Node.js / NestJS
Creation of complete and structured web applications
API integration and business logic
Performance optimization and SEO best practices
My approach

I build complete projects, not just isolated components
I prioritize clarity, maintainability, and performance
I adopt a product logic: understand the need before coding
I am oriented towards concrete and iterative delivery
Why work with me?

Because you need a developer capable of transforming an idea into a functional, clean, and scalable application — not just executing isolated tasks.
