Master System Design.Crush the Interview.
Practice architecture by building it. Design on a live canvas, work through guided labs, and solve structured problems with scored feedback on every tradeoff.
Everything around the whiteboard.
Learn the concept, drill it, then prove it under time. Six parts of one loop.
A guided path from DNS and caching up to Raft and LSM trees. Each stop tells you what to learn, then where to practice it.
Follow the roadmapHands-on systems you can run and break: load balancers, replication, consistent hashing, rate limiting. Change a knob, watch the architecture react.
Enter the labsSketch topologies with a real component library: clients, balancers, app servers, caches, queues. Pan, connect, and walk requests through your design.
Open the canvasShort, sharp questions on CAP, caching, partitioning, and consensus. Five minutes between meetings is enough for a round.
Test yourselfSpaced repetition for the facts interviews actually probe: default ports, consistency levels, replication lag tradeoffs, estimation constants.
Drill the cardsQPS, bandwidth, storage, and instance counts in seconds. Built for the whiteboard moment when the interviewer asks how much data that really is.
