- Developed and shipped 30+ REST APIs across Purchase Orders, Inventory, Refunds, and Warehouse Operations; built SKU search and Redis cache-invalidation layers.
- Implemented the end-to-end warehouse fulfillment flow (PO → GRN → Putaway → Picklist → Manifest) and debugged webhook delivery across 4 order types (prepaid, COD, try-and-buy, returns).
May 2025 – Jan 2026
- Developed cross-platform production features using Next.js, React Native, Node.js, and PostgreSQL across multiple B2B SaaS applications.
- Engineered PhonePe subscription billing, role-based access control (RBAC), AI-powered email generation, and CSV lead-import pipelines.
- Integrated AWS S3, CloudWatch, GA4 analytics, and Hygraph CMS; improved Core Web Vitals through SSR optimization and lazy loading.
