Fundamentals

Algorithms Worth Revisiting

Sorting, searching, and classic structures are not interview trivia—they are lenses for naming, splitting, and testing the code you ship every week.

Interfaces

APIs People Actually Use

Good Java APIs hide complexity without hiding surprises—naming, error models, and evolution strategy matter as much as any framework choice.

Craft

Mistakes That Scale

Null handling, exception sprawl, and mutable shared state compound quietly—catch the patterns early before they become production folklore.

Core Algorithms

How brushing up on classic algorithms changed structure, readability, and performance instincts in real Java code.

API Design

Why empathy for callers—and patience with versioning—still separates libraries teams love from ones they tolerate.

Coding Pitfalls

Frequent Java foot-guns and the habits that prevent them from spreading through a codebase.
