About Joffrey

Web developer with several years of experience in agencies, I offer my skills as a freelancer to support your web projects in a reliable, clear, and structured manner.

I design and develop custom websites, both front-end and back-end, with a strong emphasis on code quality, maintainability, accessibility, and mobile adaptability. My approach is both technical and pragmatic: to deliver robust, useful solutions aligned with the client's concrete expectations.

Key technical skills:
- PHP Development: from scratch, Symfony, WordPress
- Responsive and accessible HTML / CSS / JavaScript integration
- Creation, customization, and optimization of WordPress sites
- Technical maintenance, functional enhancements, bug fixing

My services include clear documentation, clean deliverables, and rigorous follow-up. I pay particular attention to details and the quality of the user experience, whether in terms of interface, performance, or compatibility.

I can also assist freelancers and small businesses in establishing an effective, sustainable, and easy-to-manage web presence.
