Hi, My name is Hasnain. I've read and understood the project specifications, I'm assuming that you had a working solution of Instagram connectivity with your webapp and yes Instagram/Facebook recently updated their APIs and the old 3rd party plugins are void now. Well, You'll have to use new APIs to get the functionality back.
Well, I'm available to work on this project. As for my technical background, I've over 3 years of web development experience. I'm currently working as a software engineer in a Swedish company here in Pakistan. I mostly use Python and PHP for my web development projects. I've developed several business/portfolio websites powered by Wordpress. I've experience in frontend development stacks including Angular, React & jQuery as well. I'd love to get more details from you about the project, send me a message.
