HI!
I'm Marllon Sóstenes
Your Web Experts
I'm a Brazilian developer who develops apps, websites and software in general. My focus is on mobile, developing apps for Android and iOS with Kotlin and Swift and hybrids with Flutter. For backend I mainly use Javascript and its variations and Java. In addition to gaining more Flutter experience, I'm also working on broadening my skills in React and React Native.
