The system runs on AWS Spot Instances spare compute capacity that can disappear at any moment, yet our system is built to stay online without any interruption for the user. Backed by Kubernetes with event-driven autoscaling, everything is tuned for millisecond-level data retrieval so the experience never feels slow, even at 200 million monthly visits . The frontend is built on React and Vite , leveraging Code Splitting and Tree Shaking to keep core bundles lean and Time to Interactive under a second.
