  • Scalability & Reliability:
    • Design systems that can scale horizontally under heavy load.
    • Ensure fault tolerance, failover mechanisms, and efficient resource utilization.
    • Build observability into services with metrics, tracing, and alerts.

  • Proven expertise in designing and implementing microservices and API-driven architectures.
  • Hands-on experience building low-latency, high-performance systems (sub-100ms response targets).
