  • Ensure solutions align with AWS Well-Architected Framework principles, modern CI/CD practices, API-first design, event-driven architecture, and cloud-native engineering standards.
  • Lead technical decision-making, evaluate design tradeoffs, provide escalation support, and guide implementation across multiple concurrent initiatives.
