E-Commerce Performance: 800ms to 120ms API
Reduced API response times by 85% and enabled a marketplace to scale to 50,000 daily active users without infrastructure cost increases.
Business Context
The problem space and success criteria
A growing e-commerce marketplace was suffering under its own success — slow APIs, frequent timeouts, and an architecture that couldn't support new vendor onboarding.
Project goals
- Reduce average API response time below 150ms
- Implement horizontal scaling without code rewrites
- Add multi-vendor support without data leakage risks
- Build comprehensive API documentation for mobile team
Technical Response
How the delivery was structured
Solution
Introduced a service-layer architecture, aggressive Redis caching, database query optimization, and AWS Lambda for async processing.
Architecture
Laravel API → MySQL (optimized indexes) → Redis (query cache + sessions) → AWS Lambda (image processing) → CloudFront CDN

API response time: 800ms → 120ms (85% reduction)
- Scaled from 10k to 50k daily active users
- Infrastructure cost held flat despite 5x traffic growth
- Zero vendor data leakage incidents
