Principles for designing interfaces — whether REST endpoints, component inputs, or module boundaries — that minimize what callers need to know while keeping implementations free to evolve.

Developer tooling spans the full surface area of software construction — version control, testing, shell ergonomics, AI coding assistants, and platform infrastructure — with a consistent theme: reducing friction without sacrificing correctness or security.

Engineering craft is the accumulated discipline of writing, organizing, and maintaining software well — spanning code design, tooling fluency, communication, and the judgment to know when technical excellence actually changes outcomes.

The engineering decisions that determine how software behaves under real load, covering durability, observability, testing discipline, performance constraints, and the operational costs of failure.

Software engineering spans craft, process, and judgment — how code is structured, tested, reviewed, deployed, and maintained — and the sources collected here collectively interrogate each layer as AI tooling reshapes who does what and why.
