Open Source

I've been building and collaborating to open source software since the beginning of my engineering career. My current focus is on React and React Native, having contributed to both technologies. I have also built OSS that has been downloaded more than 5 million times and it's used by more than 25.000 projects.


I have several publications in different types of media on Internet. I published two React Native courses on PacktPub: Building your application with React Native and Publishing your application with React Native. I'm also an active StackOverflow user, you can check my profile and reputation here.
