Studio Pret
3 million daily requests handled with approximately 0 errors.
Continuous client requests processed daily without connection limits or database crashes.
Live sales transactions settled on edge database instances under massive concurrency pressure.
Database Lockups
Studio Pret's e-commerce storefront crashed consistently during collection launches. Their legacy database connections locked up under concurrent traffic, resulting in lost shopping carts and abandoned checkout flows.
Edge Serverless Rebuild
We rebuilt the application using Svelte and migrated the backend entirely to Cloudflare's serverless platform. By utilizing Cloudflare D1 for transactional data and Cloudflare KV for high-speed catalog caching, the platform now handles massive traffic spikes automatically.
Execution Path
Audit & Simulation: Stress-tested the legacy backend to locate connection bottlenecks.
Database Migration: Refactored database schemas to run efficiently on D1 SQL.
Svelte Frontend Implementation: Engineered an optimized checkout flow with minimal script overhead.
Cutover: Executed a zero-downtime migration under live production traffic.
"Kryft took a system that was bleeding revenue every launch and stabilized it. We haven't had a database crash since."

Under-the-hood Challenge
Replicating ACID transactional behavior across edge nodes without adding round-trip latency. We addressed this by batching mutations at the edge node nearest to the transactional boundary.
