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.

Reliability in software systems is achieved through structural constraints and environmental design rather than prompting, validation, or testing alone, as sources from agent engineering to durable execution consistently show.

Software architecture shapes how systems behave under pressure, how teams reason about codebases, and how much complexity accumulates over time — spanning module design, state management, deployment topology, and the feedback loops that keep all three honest.
