(About)

A technical partner, not just a contractor.

I’m Jatniel Guzmán, a freelance PHP backend developer based in France, specialized in Symfony, Laravel, and PrestaShop. For more than 20 years, I’ve been building web applications, APIs, and e-commerce solutions for businesses looking for solid, maintainable solutions built to last.

My approach is simple: understand your business needs, technical constraints, and real priorities in order to build the right solution - not just deliver code.

Whether it’s a full project or team augmentation, I work with the same level of commitment to code quality, performance, security, and clear communication.
