Experience
Software Engineer II
Walmart Global Tech · Sunnyvale, CA
- Architected and extended React-based microfrontends using Module Federation for enterprise Sourcing and Product Lifecycle Management (PLM) platforms, enabling a host application monorepo to expose itself as a remote while consuming multiple federated microfrontends to support scalable, runtime-composed user experiences.
- Developed a dynamic, federated UI for an AI-powered agentic experience, delivering a chat-based interface with full functional parity to an existing agent system and owning end-to-end frontend architecture, state management, and integration within the sourcing platform.
- Enabled parallel development and independent deployment of agent UI capabilities by decoupling features into federated microfrontends, reducing integration friction and accelerating feature iteration across teams.
Software Engineer Intern
Walmart Global Tech · Bentonville, AR
- Enhanced an enterprise Sourcing and PLM insights dashboard by implementing advanced UI customizability features, including drag-and-drop layouts, component resizing, and conditional visibility, significantly improving flexibility and user experience.
- Implemented persistence for personalized dashboard layouts across sessions, extending APIs to support both local and Module Federation microfrontends.
- Contributed to CI/CD pipelines by deploying frontend and backend updates reliably, improving release cadence and streamlining delivery of new dashboard features.
Software Development Engineer Intern
Amazon · Seattle, WA
- Enhanced search functionality in an HR analytics platform by implementing advanced filters based on employee and organizational attributes, improving usability and the precision of recommendations.
- Extended GraphQL queries, backend APIs, and React frontend integration to support dynamic, data-driven filtering, ensuring efficient data flow and more personalized employee growth insights.
- Improved software quality and release reliability by writing unit tests with Jest and Enzyme and deploying features through an AWS-based CI/CD pipeline.
