Master System Design & Algorithms
Curated learning paths — System Design, Data Structures & Algorithms, Databases, Java & Spring Boot, and Kubernetes — built for engineers who want to go deep.
Low Level Design
Master object-oriented design, design patterns, and SOLID principles through real-world system design problems.
High Level Design
Learn to architect distributed systems, design scalable APIs, and make the right trade-offs for production systems.
Data Structures & Algorithms
Build a strong foundation in algorithms and data structures — from arrays to dynamic programming and graph theory.
Databases
Deep dive into relational and non-relational databases — indexing, query optimization, transactions, and scaling strategies.
Java & Spring Boot
Learn Java fundamentals and object-oriented programming, then build production-ready REST APIs and microservices with Spring Boot.
Kubernetes
Learn container orchestration from first principles — pods, deployments, services, and the patterns behind running real workloads in production.
Visual Roadmaps
See your full learning path as an interactive graph. Know exactly where you are and what comes next.
Progress Tracking
Mark lessons complete. Pick up exactly where you left off, even across sessions.
Depth Over Breadth
Each lesson is written to give you a real mental model, not just surface-level definitions.
