How I Work
Engineering Principles
Design Contracts First
Define data models and error contracts before writing implementation code.
Build Iteratively
Ship small, testable slices with clear acceptance criteria at each step.
Automate Guardrails
Linters, formatters, and tests keep code healthy without manual effort.
Document Essentials
README, API endpoints, environment variables, and deployment runbooks.
“Simplicity is prerequisite for reliability.”
