SRE Manager | Data Platform Infrastructure

Architected and governed SLOs for more than 3,000 servers supporting enterprise data warehouse analytics workloads, achieving a 99.9% success rate, four-hour RTO, and 15-minute RPO. Operated Kafka clusters, monitored Spark workloads on Azure Databricks and Hadoop, and managed Airflow DAGs across hybrid infrastructure.

Reduced critical incident MTTR by 40% through Prometheus and Grafana alerting and automated remediation runbooks. Led ITIL v4 P1 incident response, RCA, recurrence prevention, Kubernetes monitoring, and hybrid cloud observability. Automated migration and failover processes with Python and Kubernetes tooling, reducing cutover time by 35%.

Hired and onboarded eight SRE engineers, led cross-functional teams of more than 55 people across six APAC countries, managed a $2 million annual infrastructure budget, and established technical development and AI-assisted engineering governance programs.

Led SLO definition and reliability engineering for more than 1,500 business-critical application migrations across three countries, achieving 99.95% availability and less than 30 minutes of downtime. Executed IaaS, PaaS, and SaaS migration strategies with SQL database transformations and CI/CD integration.

Validated post-migration performance, including sub-150ms 95th percentile latency and error rates below 0.1%. Troubleshot Kafka consumer lag and Spark streaming failures and configured Azure Application Insights for real-time monitoring.

Managed schema and stored procedure migrations for more than 200 OLTP databases, supported Airflow ETL cutover validation, and developed Python reconciliation scripts. Ensured GDPR and MAS TRM compliance through encryption, Azure Key Vault controls, TLS 1.3, and security hardening reviews.
