• API security fundamentals: OAuth 2.0 (client credentials, on-behalf-of / token exchange), JWT issuance and verification, JWKS rotation and caching, secrets handling.

• Microservices architecture experience: service-to-service auth, structured error/result handling across service boundaries, fail-open vs. fail-closed reasoning under a latency budget.

• Reads an unfamiliar, unmaintained codebase quickly and cites module and line in every claim; works from written acceptance criteria without supervision.

Nice to have
