Work Experience
2022 - 2024
Software Engineer - Mastercard
As a Frontend Engineer on Mastercard's Click to Pay initiative, I developed a custom analytics class to centralize data logging, reducing redundancy across UIs. I overhauled authentication, transitioning from cookie-based to token-based for enhanced security, and maintained a reusable UI component library to streamline development. I optimized state management, improving performance and accessibility of critical application states. Additionally, I implemented robust testing (unit, end-to-end, visual) using Jest and Cypress, created systems architecture diagrams for frontend-backend workflows, and provided on-call support for critical issues.
