Build an AI Agent Task Queue with Resumability Premium
Design an agent execution framework that handles long-running tool calls, persists agent state so tasks can be paused and resumed across server restarts, enforces token and cost caps, and supports parallel sub-agent execution.
Build a Change Data Capture Pipeline Premium
Design a CDC pipeline that streams every database write to downstream consumers in the order they occurred, preserves transactional boundaries, and guarantees no event is dropped even if a consumer is temporarily offline.
Build a Chaos Engineering Platform Premium
Design a controlled failure injection platform that safely introduces latency, packet loss, and resource exhaustion into production services, enforces blast radius limits, and automatically halts experiments when SLOs degrade.
Build a CI/CD Pipeline Orchestrator Premium
Design a system that handles 10,000 concurrent build and test jobs, assigns them to workers, streams logs in real-time, and ensures no job is lost even if a worker crashes mid-run.
Build a Concurrent Device Session Manager Premium
Design a session enforcement system that limits streaming to N concurrent devices per subscription plan, kicks the oldest session when the limit is exceeded, and works correctly across distributed servers.
Build a Distributed Code Execution Runtime Free
Design a secure, sandboxed code execution engine that compiles and runs untrusted user code in multiple languages, returns output within seconds, and scales to thousands of concurrent submissions.
Build a Distributed Cron Job Scheduler Premium
Design a cron scheduler that guarantees exactly-once execution of jobs across a cluster of nodes, handles missed executions during downtime, and scales to millions of scheduled tasks.
Build a Distributed Key-Value Store Premium
Design a distributed KV store that partitions data using consistent hashing, replicates each key across N nodes for durability, and handles node failures with tunable consistency guarantees.
Build a Distributed Lock Manager and Leader Election Service Premium
Design a distributed coordination service that provides mutual exclusion across a cluster, implements lease-based locks that expire on node failure, and enables leader election for singleton workloads.
Build a Distributed Rate Limiter Across 100+ API Gateway Nodes Premium
Design a rate limiter that enforces per-user and per-tenant request limits globally across a horizontally scaled API gateway fleet, with no single coordinator bottleneck and sub-milliseclient enforcement latency.
