    Passionate and dedicated to mobile development since 2016. Have an app design or idea that you want to launch to the iOS/Android stores? Contact me and let's talk about it! I love to hear about new apps, I really do, and even more if it's an original and creative idea you have in mind. Be either simple or complex project, I can assure that I have the right qualifications to complete your project without any hassle. As you might have realized I am an entrepreneur myself and want to help YOU launch your app (aka your business) to the real world. My current expertise is focused on mobile development with React Native, which is a hybrid technology to create native looking iOS and Android apps. And if you want to take your project to the next level, I know very well how to implement smoothly backend services with Firebase, like: - User Authentication: methods such as Email/Password, Google, Facebook, Apple... or even Anonymous - Cloud Firestore: scalable database (NoSQL) to play with app data - Cloud Storage: save on the cloud images/audio files to use in the app - Analytics: understand how your users are using your app - Crashlytics: track the app crashes that a user may have - Cloud Messaging: customized push notifications for your users - Dynamic Link: create a smart link for marketing purposes that opens web/iOS/Android app depending on device Yeah! I'm in love with Firebase, it's such a complete set of tools for your app. And what's even better, there are no service costs if your project is not above a certain amount of daily interactions. Thank you Google! To throw in some numbers, you would have to surpass 50k read operations per day or 20k write operations per day to start receiving some invoices, which are not high at all. Indeed, I am aware of best practices to design the most optimal database for your app with Cloud Firestore, to reduce the daily rate of Write/Read operations and maintain that free quota as long as possible. Not convinced yet? I'll show you proof of my work as a senior React Native developer (see my portfolio) and also my GitHub account to see some small open-source projects. Do I have knowledge about other technologies? Of course yes! As a developer you have to keep updated to be where you want to be and never settle down. Improving every day with best practices, clean code, clean architecture and test-driven development. My full potential is with React Native and that's why I'm focused on it right now. But I didn't start with hybrid mobile development because I didn't own a MacOS at that time, I started developing native Android apps with Java, I keep doing it because I love to work on my already launched projects as an entrepreneur. Also built some really complex apps for clients in native Android. During my time working for an agency I also learnt developing web apps using Django + Python + MongoDB. It was really easy for me to adapt coming from mobile development. Despite enjoying this kind of web development too, I enjoy a lot more the mobile world. That's the reason I will only work at my best skills, which are React Native + Firebase. Want to have a chat with me? Me too! Please contact me with details about your new mobile app. I appreciate you took the time to read my profile.
