The brief

Accelerate feature velocity on Porter's All India Parcel / Courier product — a WebView-based booking experience within the Porter super-app — covering the full shipper journey from booking to post-order management, while also ensuring platform reliability through API gateway migration and iOS parity.

What we built

A comprehensive React JS courier booking and management platform embedded as a WebView within Porter's native logistics app. Key deliverables include:

  • full end-to-end courier booking flow (pickup/drop address, package details, quotation, review, payment, post-order)
  • coupon/discount/auto-discount engine with GST-accurate pricing
  • e-waybill generation module with OCR fallback and 2FA
  • dual payment gateway (Juspay primary + Razorpay fallback) with iOS/Android parity
  • CAG (Central API Gateway) migration of all courier APIs
  • CMS-driven dynamic landing page
  • recent search and saved address features
  • next-day delivery and EDD display with holiday calendar integration
  • courier rebooking flow
  • shipment insurance (AB tested)
  • CFMS franchise management dashboard testing, and
  • AWS-to-GCP database migration validation. All features released with rollout flags and AB testing gates.
⊛ Live in production

Courier booking flow (web + app entry points), coupon/discount engine, e-waybill module, Juspay+Razorpay dual gateway, CAG-migrated APIs (100% rollout), CMS landing page, recent search, next-day delivery, rebooking flow, shipment insurance (AB test), and CFMS dashboard are all live on production. Saved address and EDD revisions are in AB testing. GCP migration cutover completed.
