SOLID Principles in Practice
Apply all five SOLID principles to a small checkout design, see where they help, and learn when extra interfaces or indirection make code harder to change.
The Strangler Fig Pattern for Incremental Modernization
Use the Strangler Fig pattern to replace legacy capabilities incrementally with routing, data ownership, observability, and rollback plans.
Structural Patterns: Compose Objects and Interfaces
Compare Adapter, Bridge, Composite, Decorator, Facade, Flyweight, and Proxy with Java examples, costs, failure modes, and guidance for choosing a fit.
Tell, Don't Ask and the Law of Demeter
Apply Tell, Don't Ask and the Law of Demeter to keep object rules near their data, reduce fragile navigation, and see when a direct query is clearer in context.
Testable Object Design and Collaborator Seams
Learn to design object-oriented code around behavior, collaborator boundaries, and stable dependency seams, with practical tests that resist refactoring churn.
Value Objects, Entities, and Aggregates
Learn how identity, value equality, and aggregate boundaries shape a reliable order model, with Java code, trade-offs, failure cases, and design checks.
Computer Networks Roadmap
Learn how networks move data, from Ethernet and IP addressing to TCP, DNS, HTTPS, routing, security, and practical troubleshooting in production.
Event-Driven Architecture Roadmap: From Events to Production
Follow a practical path through event-driven design, brokers, contracts, reliable delivery, workflows, stream processing, and production operations.
Network Encapsulation: Follow a Packet Across the Stack
Follow an HTTPS request from a browser through transport, IP, and link layers, and learn how headers, MTU, routers, and packet captures fit together.
