Work Experience

Software Development Engineer I

WizCommerce

Jan 2025 - Jan 2026

Built the Review Order and Order Submission pages for Ella, an AI-powered platform that converts customer purchase orders into structured order drafts for review before submission. Designed workflows for reviewing and editing AI-extracted data (buyer details, products, pricing, quantities, discounts, custom attributes), keeping field-level updates accurate across AI-extracted, system-generated and user-edited sources. Implemented prefill, autosave, catalog/contract pricing, business validations, eligibility checks, error handling and resubmission flows. Implemented Pusher-driven real-time updates, notifications and embedded iframe workflows; resolved production issues with backend and QA teams. Optimized Review Order page performance by using Chrome DevTools to find API sequencing and blocking operations delaying draft rendering. Developed reusable React component libraries with built-in validation, improving UI consistency and reducing duplicate implementation across applications. Built tenant-level configurations and feature-based customizations, letting each tenant enable the workflows and features its business needs. Implemented custom sorting for Collection, Category and Product segments using AG Grid Tree Data, supporting hierarchical views, intuitive navigation and business-specific ordering. Implemented and debugged complex order scenarios involving multiple POs, line-item changes, pricing/discount updates and validation.
