What This Blog Is About
AI tools like Copilot and ChatGPT write code fast. But code quality still matters. This blog is about the stuff AI still gets wrong:
- Mutability — why val over var, and when immutability saves you
- Code smells — obvious bugs hiding in plain sight
- Kotlin patterns — extension functions, scope functions, and when they hurt readability
- Java to Kotlin — real migration lessons, not just syntax
- AI-assisted development — what works, what doesn't
No fluff. Real examples from production code.
