#177 - Simple Object-Oriented Design: Principles for Writing Clean & Maintainable Software - Mauricio Aniche

“Every software gets more complex over time. What we need to do as engineers is to find ways so that we can work with increasing complexity, but not increasing the cost of maintaining the software." Mauricio Aniche returns to the podcast for the second time and discuss with me his latest book, “Simple Object-Oriented Design”. Our discussion explores the intricacies of software design and shares practical strategies to manage software complexity through effective object-oriented design. Mauricio delves into the six key principles of a simple object-oriented design: making code small, keeping objects consistent, managing dependencies, designing good abstractions, handling external dependencies, and achieving modularisation. This episode is a must-listen for anyone seeking to deepen their understanding of object-oriented design and maintaining simplicity in their codebase!   Listen out for: Simple Object-Oriented Design Book - [00:03:19] No Perfect Code Design - [00:04:51] Managing Complexity - [00:06:37] Object-Oriented Design - [00:08:24] Design as an Everyday Activity - [00:09:43] Effective Iterative Design - [00:12:31] Refactoring - [00:14:31] 6 Principles of a Simple Object-Oriented Design - [00:16:40] Principle #1: Making Code Small - [00:21:06] Arguments Against Smaller Units - [00:23:18] Principle #2: Keeping Objects Consistent - [00:26:25] Don’t Fight Your Framework - [00:30:03] Principle #3: Managing Dependencies - [00:32:05] Separate High-Level (What) and Low-Level Code (How) - [00:33:34] Principle #4: Designing Good Abstractions - [00:36:31] Finding the Balance in Abstraction - [00:38:39] Principle #5: Handling External Dependencies and Infrastructure - [00:41:05] Principle #6: Achieving Modularisation - [00:45:12] Owing to Junior Developers - [00:49:18] 3 Tech Lead Wisdom - [00:50:32] _____ Mauricio Aniche’s BioDr. Maurício Aniche’s life mission is to help software engineers to become better and more productive.
