• Design, optimize, and maintain complex relational databases (MySQL, PostgreSQL, Oracle), including complex SQL tuning, indexing strategies, and database sharding or partitioning.
• Architect and manage cloud infrastructure and deployment pipelines using Docker, Kubernetes (K8s), and AWS services (EC2, EKS, RDS, SQS/SNS, Lambda).
• Set up and maintain system observability, central logging, and distributed tracing solutions (Prometheus, Grafana, Datadog, ELK Stack, Jaeger) to guarantee high availability and performance.
• Mentor junior and mid-level engineers through regular code reviews, technical guidance, and team knowledge-sharing sessions.
• Lead troubleshooting, root-cause analysis (RCA), and resolution of high-severity production incidents, performance bottlenecks, and security vulnerabilities.
• Collaborate closely with cross-functional teams, technical leads, and stakeholders to refine requirement scope, provide technical estimates, and drive system improvements.
