ScaleDojo | Interactive System Design Practice Platform
ScaleDojo is an interactive, hands-on learning platform for system design, software architecture, API design, database schema design, and generative AI pipelines. Learn by building real distributed architectures, modeling schemas, and designing production-ready APIs with instant AI feedback.
Interactive System Design Labs
- HLD Architecture Lab: Design distributed cloud architectures on a drag-and-drop canvas. Connect load balancers, CDN nodes, databases, message queues, caches, and workers. Practice on 70 challenges including URL shortener, rate limiter, notification system, and consistent hashing.
- LLD Schema Design Lab: Practice database schema modeling on an interactive ER canvas. Define tables, keys, fields, data types, constraints, and forge schema relationships. Complete 50 normalized relational missions.
- API Design Lab: Master REST API design across 50 progressive levels. Craft endpoints, model request/response payloads, specify correct HTTP status codes, handle nested structures, implement query parameters, pagination, and error responses.
- GenAI Systems Lab: Design production-grade Generative AI pipelines and LLM application architectures. Architect Retrieval-Augmented Generation (RAG) pipelines, design autonomous AI agents, prompt templates, vector databases, model routers, and guardrails.
