How Picsart leverages Cloudflare's Developer Platform to build globally performant services

Cloudflare describes how Picsart migrated its remote configuration/experimentation service to Workers and Workers KV to minimize network latency, including sharding data by platform and country, using immutable KV records with hashed keys, separating lightweight metadata from large JSON values, and adding client-side preconnect/initialization improvements; the rollout reduced global median response times from ~1500 ms to ~280 ms (to ~70 ms on web) and increased successful experiment delivery from 50% to 85%, enabling faster, more personalized user experiences at global scale.
