If you are looking to build out a mobile web application, then I can do this for you without a problem using React. If you are looking for an ios or android specific app, where you need React Native, then that is something I can't help with. I'm in the U.S. and would be able to communicate with you when needed. I will be using React and its ecosystem to framework the application, and SCSS and CSS for styling and mobile responsive design. Do you have a design for the project already? Also, for a blogging app, you will need a database and a server, as well. So those will need to be set up. I used Node.js for server setup and MongoDB or MySQL for the Database, but can do another if you prefer. Looking forward to working together, and I hope to hear from you. Have a nice day.
