Hello Dear.
I read your job description carefully. I can do your project.
As for me, JavaScript is a piece of cake. I have a lot of experience in JavaScript Framework like Vue.js , Angular.js , React.js and etc.
Specially I am interested in Angular.js. it is very fun.
Please look my profile. I have experience in develop ionic project that use angular.js
Perhaps I can say I have mastered in this field.
Please contact me and let's discuss more detail.
Thank & Regard.
