I use Python primarily nowadays.
I've previously worked with Django on several small projects and now trying out Flask. I have some experience with front end web development as well. Been using Mongodb for the past few months and am quite happy with it so far.
I also developed an iOS app with Swift and node.js named GeeksforGeeks Reader, which has good reviews in the U.S. App Store.
I'm interested in working with Swift, node.js more in the future.
