Context
The previous marketplace was slowing down as sellers and product counts grew.
Challenge
Host hundreds of shops and live stock counts on one platform without one busy seller degrading the others.
Non-negotiables
- Concurrent traffic
- Secure payments
- Real-time inventory
Calls I made
- 01
Per-shop isolation
Pulled per-shop logic out of the shared path so a slow vendor does not affect the rest of the marketplace.
- 02
In-memory catalogue cache
Hot product data lives in memory. Shoppers see pages load quickly; database load drops.
Trade-offs accepted
- Tightened seller onboarding to capture clean, structured data on day one. More friction up front, less cleanup later.
- Kept front-end visuals lean. Page speed was the higher priority.
Outcome
Page loads dropped sharply at p95 and peak traffic stopped degrading shop pages.
