CORE PRINCIPLES
  • Clean architecture over clever code — readability compounds.
  • Every API is a product. Design it for the consumer, not the implementer.
  • Testing is not overhead; it is the specification made executable.
  • Deploy early, deploy often — CI/CD as a first-class engineering practice.
  • Horizontal scaling is designed upfront, not bolted on under pressure.
  • Security by design: threat-model before you type a single line.

API-First Design
Contracts defined before implementation. OpenAPI spec as source of truth for every endpoint.
Secure by Default
RBAC, JWT auth, HTTPS-only, and rate limiting applied on every public-facing endpoint.
Cache-Aside Pattern
Redis as L2 cache with targeted invalidation. PostgreSQL stays the source of truth.
Observable System
Structured JSON logging, Sentry error tracking, and health check endpoints from day one.
