• Define and evolve system architecture for multi-region, highly available deployments across AWS and on-premise infrastructure.
• Deliver performant APIs and control systems for secure, large-scale connectivity and real-time workloads.
• Design for high Concurrent User (CCU) loads, focusing on throughput, latency reduction, and horizontal scalability.
• Leverage Redis for caching, distributed coordination, and Pub/Sub messaging.
• Use Kafka for scalable event streaming, log aggregation, and operational analytics.
• Conduct performance tuning, load testing, and fault injection to validate system resilience.
• Embed strong cryptographic and secure communication practices (key exchange, rotation, encryption in transit and at rest).
• Collaborate with security stakeholders to align with compliance standards (SOC2, ISO 27001, GDPR).
• Implement CI/CD pipelines, Infrastructure as Code (Terraform, Ansible), and GitOps workflows.
• Manage Kubernetes clusters (AWS EKS and on-prem) for containerized workloads, ensuring scalability and high availability.
• Drive observability with metrics, logs, and traces (Prometheus, Grafana, OpenTelemetry).
• Provide hands-on technical leadership and mentor engineering team members.
• Guide design reviews, enforce coding standards, and foster a culture of technical excellence.
• Partner with Product and Operations teams to translate requirements into scalable solutions.
