Work Experience

Full Stack Developer

CedCommerce – Threecolts India Pvt Ltd

Jan 2020 - Present Uttar Pradesh, India
  • Architected a micro frontend architecture using Module Federation (Webpack 5), decomposing a monolithic catalog and order management system into independently deployable micro-apps and reducing cross-team deployment dependencies by 60 percent.
  • Designed a shared React component library consumed across catalog, order, and user micro frontends, enforcing consistent UI contracts and cutting duplicated code by 35 percent.
  • Established inter-app communication using a custom event bus and shared state contracts, allowing loosely coupled micro frontends to synchronize inventory and order status independently.
  • Led the migration from a monolithic React codebase to micro frontends, defining team ownership boundaries, versioning conventions, and per-service CI/CD pipelines, improving release cadence across three product teams.
  • Developed and maintained scalable web applications for product, order, and client management using React.js and TypeScript, increasing deployment speed by 40 percent.
  • Engineered a reusable TypeScript component library that boosted user engagement by 25 percent and improved interface responsiveness by 30 percent.
  • Spearheaded a real-time customer support tool that reduced average issue resolution time by 20 percent.
  • Configured Sentry across all production frontends for error tracking and proactive performance monitoring.
  • Mentored and onboarded junior developers, raising overall team productivity by 20 percent.

Projects

Shopify VidaXL Integration

  • Developed a Shopify application enabling merchants to connect their VidaXL dropshipping account and list VidaXL catalog products on their storefront without holding physical inventory.
  • Designed an onboarding flow with React.js and TypeScript, allowing users to authenticate via OAuth2 and configure product sync preferences through a guided multi-step wizard.
  • Automated product import, stock level synchronization, and order forwarding to VidaXL’s fulfillment pipeline using REST APIs and Node.js webhook listeners.
  • Created a dynamic category-mapping interface with React Query and Zustand so merchants can map VidaXL categories to Shopify collections and apply custom pricing rules.
