My approach is simple: understand the problem, make deliberate decisions and build something people can maintain.

Keep It Simple

Build the simplest solution that solves the real problem. Every layer should earn its place.

Make It Understandable

Write code the next engineer can read, maintain and improve. Share the reasoning, not just the result.

Stay Close to the User

Break complex problems into focused questions and connect technical decisions to the people they serve.
