Hi,
I have very good expertise in developing ReactJs, NodeJs, MongoDB App web application as well as React Native mobile application. Also have familiarity with infrastructure like Amazon, Google App Engine as I have leveraged these for some of our projects. I have also integrated PayTm as the payment gateway.
Have used most of the React packages related to authentication/authorization/migration/extensions/push-notification, social media and many more. Have experience with databases like MySQL, and mongo.
