Sergio Expósito
Fullstack Mobile App Developer
About me
I'm Sergio, a fullstack developer specialized in mobile applications. Since 2023 I've worked at Hyliacom building cross-platform apps with Flutter, along with desktop solutions and backend services on EasyClient, an in-house framework developed with PHP and MySQL.
I enjoy building polished products with great performance and attention to detail, and I'm always learning new technologies —from Dart and TypeScript to React, Angular or Laravel— to give my best on every project.
