Stripe in Angular 1.5 site - 3D Secure enhacement

We have a web application that is a booking platform for hotels and travel packages. The main part is developed in Angular 1.5 with Typescript. To make reservations we have an booking form with Stripe for deal with card payments. Currently this works well, but we want to add an extra layer of security by applying 3D Secure from Stripe. The platform can be accessed by launching a search from: [login to view URL] When you launch the search you are redirected to the sub-domain [login to view URL] which is the part under Angular. Regarding with the code repository, we work with bitbucket. Scope Implement the necessary changes according to the Stripe documentation to use 3D Secure, on a bitbucket branch: [login to view URL] There are different ways to make the reservation depending on the rate chosen by the client: Prepaid card mode Cancelable mode with card Cancelable mode with bank transfer The 3D Secure payment system should only be used in the case of "Card Prepaid Mode". Search profile We are looking for a freelance backend developer with knowledge of Angular, Node and SQL. If the result of the first job is good and the hourly rate is reasonable, we would like to collaborate in the longer term with a list of more complex evolutions that we have planned.
