Great advantage is English is the only language for communication

FE: HTML5, CSS3, BEM, Sass, JS ES6, React, Redux, Formik.
BE: GraphQL, (Webpack, Babel, Github, Yarn)
2) Trawelo: a Javascript-heavy travel app with a clean UI. It targets the DOM, working with 3 objects, and retrieving data from 3 APIs each of which is reliant on another to work. It's all done in a webpack environment, using an express server, and wrapped up with service workers
3) YouTube clone: Used REACT (Router), Material UI (design), Firebase (host data real time), CSS Flexbox. It doesn't refresh when you search for videos so its fast.
On top of that, I am one of the very few (probably 0.1%) people in Central Asia who were able to get a perfect band 9.0 in IELTS Speaking Test by doing self-study and without taking any English courses or classes. This shows that I'm pretty good at learning.
I have also been able to help hundreds of people learn English and web development and get into the university of their dreams, immigrate to another country or get international jobs. This shows that I'm good at sharing what I've learned and help the people around me.
