Define data contracts, schema evolution strategies, and idempotent/eventual consistency patterns
Embed AppSec best practices, OWASP controls, secure API/auth (OAuth2/OIDC), and zero trust patterns
Ensure compliance with regulatory and audit requirements where applicable
Translate business needs into technical roadmaps and architecture runway
Communicate trade-offs and decisions to both technical and non-technical audiences
