Drive or contribute to technical decisions involving architecture patterns, technology selection, security, data design, and integration approaches. Maintain awareness of industry trends and evaluate relevant tools, frameworks, languages, and AI-assisted development practices. Use approved AI tools as active components of the daily development workflow to accelerate implementation, debugging, testing, documentation, dashboards, backend logic, and integrations; critically evaluate AI-generated output for security, maintainability, correctness, and production readiness. Implement secure authentication and authorization using approaches such as OAuth 2.0, OpenID Connect, JWT, token-based access, signed URLs, and role- or claims-based permissions.
