Design database schemas using relational (SQL Server, PostgreSQL) and NoSQL databases appropriate to service requirements. Build caching layers using Redis or in-memory caches to reduce database load and improve response times.

Security and Compliance

Implement secure coding practices including input sanitization, SQL injection prevention, and protection against common OWASP vulnerabilities. Design authentication and authorization systems using OAuth 2.0, JWT, and identity providers (Azure AD, Auth0, etc.).
