Description

Android Developer since 2012. I have worked on all kinds of projects since then: corporate applications focused on security, cryptography and digital signature, sports apps (football results, news...), mobile games and many more.

My specialty is native Android applications, although I also develop apps in Ionic Framework (for both Android and iOS).

Throughout my career, I have also worked as a front-end web developer with HTML+CSS+JavaScript and as a back-end developer mainly with PHP+MySQL. Additionally, I have developed numerous websites with WordPress, as well as custom plugins for said CMS.

I have experience in both design and implementation of REST APIs and data exchange in web services using JSON.

I am currently available to work part-time on any project that can be proposed to me and that fits my skills and knowledge.
