I'm a upwork freelancer from U.K. I have been a very successful web and native mobile application developer for over 7 years, working for individuals all over the world. Since I have started React and React Native app development, I have been spending every spare minute writing code for the React and React Native, and learning everything on mobile application development. Additionally to development of new websites and apps, a lot of the work I do is on-going maintenance of existing popular apps. Thanks!
