**Design patterns** are proven solutions to common problems in object-oriented code. This course helps you move from “it works” to “clear and extensible” without memorizing all 23 patterns at once. You will study Singleton, Factory, Strategy, Observer, Decorator, and others through clear examples. Lessons show when a pattern helps and when it is overkill. After the course you will recognize patterns in existing code, apply them deliberately, and handle middle-level technical interviews better.
Design Patterns — course structure**Software architecture** describes how system parts connect and which trade-offs keep a project healthy. This course is for developers who want the big picture, not just their own class. You will explore layers, microservices vs monolith, APIs, events, scaling, and common anti-patterns. The material focuses on real trade-offs: simplicity versus flexibility. After the course you can join feature design discussions, defend choices in reviews, and prepare for senior or architect roles.
