Summary
I’ve started React Native development from 2 years ago - it’s announced on Jan 2015(for
iOS) and on Oct 2015(for Android).
Also, I've been developing ReactJS for 3 years, built several large-scale web apps,
customized components, web admin dashboards and have enough knowledge of
WebPack, ESLint, Babel, Yarn, Npm, Gulp, Grunt, etc
I am specialised in ReactJS, React-Native, GraphQL/Relay/Apollo, VueJS, Webix,
Redux/Mobx - I have used this library ever since its initial releases since 2015.
I focus on mobile front-end development with React-Native framework and web frontend development with React.js/Redux, HTML5, CSS3, Bootstrap, SASS/LESS, Jade,
JavaScript, jQuery, and other JavaScript frameworks & libraries.
I make it my goal to create software with the user in mind, creating applications with a
useable and intuitive user interface experience.
I also understand the importance of creating highly readable and easily maintainable
source code. I am constantly striving to learn new technologies and look to ways to better
myself in this rapidly changing industry.
