💻 About me
I am a Full-Stack Developer with 4 years of experience in creating modern and high-performance applications, using Java (Spring Boot) for back-end systems and Next.js/React for front-end interfaces.
I specialize in helping startups and SMEs to design, develop, and scale their web platforms — from MVP to production-ready SaaS solutions.
✨ What I offer
Back-end development (Java, Spring Boot) → REST APIs, authentication, microservices.
Front-end development (Next.js, React) → modern, responsive, and SEO-optimized interfaces.
Complete project cycle → architecture, development, deployment (CI/CD, Docker).
Performance optimization → scalable systems, fast loading times, secure code.
⚡ Past experiences
Development of web applications for startups.
Design of RESTful APIs used by thousands of daily users.
Reduction of loading times by 30 to 50% thanks to Next.js optimizations.
🔑 Why work with me?
Excellent balance between back-end robustness and front-end user experience.
Clear communication in French and English.
Proactive, fast, and reliable: I treat each project as if it were my own.
