Hey there, I see you’re looking for somebody who can add paypal payment gateway to your existing ASP. NET project, so one needs much enough knowledge to understand data and code flow in an existing project.
I have experience of integrating a number of APIs like, google location, sign in, facebook sign in, stripe/rojarpay/paypal payment gateway, Goibibo, jira, s3 bucket(amazon).
I have experience of more then 3 year in programming with different technologies like REACT JS, WORDPRESS, CODEIGNITER, NODE JS, ANGULAR JS, PHP, VUE JS, with 6 month full stack web developer job.
