Scaling an E-commerce Platform with AWS Microservices & Real-Time CRM Sync

Revamped our online store into independent microservices on AWS, slashing page loads and automating CRM updates.

Overview

Our flagship online store was creaking under traffic spikes and a massive product catalog—slow page loads, stock mismatches, and manual CRM syncs were hurting both UX and operations.

Challenges

  • Sub-optimal page-load times during peak traffic
  • Frequent stock discrepancies across fulfilment systems
  • Manual CRM updates causing fulfillment delays

Solutions

  • Built separate AWS Lambda + API Gateway microservices for catalog, checkout, and sessions
  • Leveraged Next.js SSR/SSG to pre-render high-traffic pages and stream the rest
  • Integrated Shopify, Zoho & HubSpot via webhooks + GraphQL for bidirectional CRM sync
  • Lazy-loaded assets and deferred render-blocking JS to boost Core Web Vitals
