Experience

1. Senior Software Engineer

   Walmart Global Tech

   Dec 2023 — Present · Bengaluru, IN

   Led the design and development of the NextGen Fee System using React, Node.js. This system empowered the business with complete control and visibility over rate contracts across various processors, enabling quick amendments through an integrated approval workflow capabilities that were previously unavailable in the legacy mainframe systems, which required heavy reliance on support teams. Additionally, we implemented alerting and dashboarding features to proactively notify the business of significant variances in fee calculations which helped us to identify $21M incorrect fee charges- Migrated Omnitran dashboard to a Micro Frontend (MFE) architecture, transforming the previously single monolithic repository into multiple independently deployable MFE services. This transition significantly improved development efficiency by reducing build and deployment times and minimizing cross-team dependencies- I developed a shared component library for the Payments teams, built using Walmart’s Living Design System. This initiative enabled consistent UI/UX patterns across all Micro Frontend services and streamlined the development process through a unified design framework- Streamlined the chargeback process by automating evidence submission to providers, resulting in daily savings of approximately an authorization solution for transactions submitted for charges and refunds using BCTranx, helping Walmart avoid substantial fines from card providers- Established a CI/CD pipeline for the existing project to streamline development and deployment processes-Focused on optimizing cloud costs to enhance efficiency and reduce expenses-Developed the URS dashboard to display the reconciliation and settlement status of each.com and in-store transaction.
