Composing objects / adapting interfaces	Design Patterns → Structural
Object communication / state management	Design Patterns → Behavioral
Service-to-service messaging	Integration Patterns
Algorithm selection / optimization	Algorithms
Code readability and maintainability	Craftsmanship
System decomposition and boundaries	Architecture
Client-side application structure	Frontend
Server-side data and API structure	Backend

Best Practices

Learn patterns as a vocabulary, not a checklist — apply them when the problem calls for it, not preemptively.
Start with the simplest architecture that works (monolith), evolve toward complexity (microservices) only when you have evidence you need it.
Apply the Boy Scout Rule: leave code better than you found it, every time you touch it.
Use SOLID principles as guardrails for daily decisions, not just for greenfield design.
Prefer composition over inheritance — most GoF patterns are variations of this principle.
Study algorithms for problem-solving intuition, not memorization — know when to reach for a graph algorithm vs. dynamic programming.
Keep integration patterns in mind whenever systems need to communicate — messaging solves problems that synchronous calls create.
