Problem framing
Clear before-and-after storytelling, with room to breathe.
Challenge
Legacy architecture stalled growth during peak demand.
The client faced massive latency issues during seasonal sales. Their legacy monolithic system couldn't handle more than 2,000 concurrent users without database deadlocks. Scaling required a complete rethink of how state and traffic were managed.
- High bounce rates during traffic spikes
- Outdated inventory sync causing overselling
Solution
A serverless-first stack unlocked speed and stability.
We implemented a serverless-first architecture using Next.js for SSR/ISR and a distributed Redis layer for real-time inventory locking. This eliminated the database bottleneck and provided sub-second page loads globally via Edge functions.
- Distributed caching for global speed
- Atomic inventory transactions with Redis
