Most bugs don’t start in methods — they start in constructors trying to do too much. Discover why logic-free constructors lead to better architecture, cleaner tests, and code that scales with humans and AI.

Utility classes seem harmless — a fast way to reuse logic and keep code tidy. But behind that convenience lies a hidden threat to your architecture. In this article, discover why Utility Classes Are Not Your Friend, which design principles they break, and how to build better, more maintainable systems instead.

Discover why string concatenation with + or . creates messy, error-prone code — and how sprintf-style formatting leads to cleaner, safer, and more maintainable software. From readability to AI assistance, here's why you should prefer string formatting over concatenation.

In modern OOP, every class is a decision. Should it be reused? Extended? Or locked down? This article introduces a simple but powerful rule: every class should be either final or abstract — never left open by accident. You'll learn why this matters for architectural clarity, how different languages support it, what design patterns and principles it promotes, and how it even improves AI-assisted development. A must-read for developers who value clean boundaries, safe code, and

Annotations are convenient — but convenience is not architecture. In this article, we explore 10 hidden drawbacks of overusing annotations and attributes, how they break core design principles, and what to do instead to build systems that are clear, testable, and AI-friendly.

Private methods might feel clean, but they often hide complexity, block reuse, and break testability. In this post, we explore why you should avoid private methods — and what to do instead for clearer, more maintainable, AI-friendly code.
