Visa, Inc. - Internship

SDE & QA Intern, Summer 2019

Developing a scalable and extensible tool to intelligently generate 1000s of test cases for 150+ gateways each having 750+ fields reducing human error and manual effort.
The tool also validates the API itself, the logicality of the rules, and coverage of all the branches.

Adding features one by one, the tool eventually got adapted to be integrated with internal system of the core payments team. The details of the implementation are now sensitive. Please request a one-time password to view.
