The Challenge

The client's legacy PHP monolith was collapsing under Black Friday traffic, causing 30-minute outages and a 60% cart abandonment rate. The codebase had zero test coverage and hadn't been refactored in 7 years.

Our Solution

We decomposed the monolith into 8 domain-driven microservices, introduced a Next.js storefront with ISR for sub-second page loads, and rebuilt the checkout flow with resilience patterns (circuit breakers, retries, fallbacks).

How We Did It

  • Full technical audit and strangler-fig migration plan in week 1
  • Domain-driven service decomposition (cart, inventory, payments, search, etc.)
  • Next.js storefront with ISR — pages served in under 200ms globally
  • PostgreSQL with read replicas + Redis caching for catalogue queries
  • Automated load testing in CI pipeline before every production release

Key Outcomes

Page load improvement (8s → 1.3s)
Conversion rate increase post-launch
99.99%Uptime on the following Black Friday
35%Reduction in hosting cost (right-sizing)
