Visa Checkout App

• Worked on the Visa Checkout App which was developed using modern web frameworks like React, Redux, Redux-Saga and included support for cross-browser as well as cross-device. Localized for 26 countries.
• Complex application that separated concerns into 3 layers. Merchant-sdk(vanilla js) which is merchant set options for the checkout experience like cards accepted, shipping/payment constraints, etc. System-sdk which launched the app and facilitated communication between the parent and child windows since our app was either an iframe or popup secure communication between the layers was needed. And last we checkout app which was the SPA UI layer of the app which was made in react and redux.
• Identified key areas in the app that needed testing. Led from scoping through implementation with several permutations for even the simplest flows. The end to end testing was implemented in Cypress and tests were not part of the CI builds; however, the tests were functionally accepted and my final project at Visa was integrating it into our Jenkins(CI) builds.
• Debugged in all modern browsers and followed industry web standard changes. Focus on cross-browser compatibility.
• Contributed code to all areas of the application including the common components. These are the foundational components that were designed to be resuable across the application.
