I spent nine years supporting UBS programs and have led the migration of more than 5,000 servers across storage, application, and cloud environments. I have consistently delivered 99.9% or higher SLO performance, reduced critical incident MTTR by 40%, and maintained strong change success rates across complex production environments. My technical expertise includes Kafka, Spark, Airflow, Kubernetes, Azure, AWS, GCP, Terraform, Python, and observability platforms such as Prometheus, Grafana, Splunk, CloudWatch, and Azure Monitor. I design SLOs, error budgets, disaster recovery strategies, and automated operational processes for real-time and batch analytics platforms. I am an experienced incident commander with strong ITIL v4 practices, including RCA completion within 48 hours, recurrence prevention, production readiness reviews, and governance for high-risk changes. I have also supported GDPR and MAS TRM compliance, encryption controls, and hybrid cloud security hardening. I have hired and developed SRE talent, led cross-functional teams of more than 55 people across six APAC countries, managed annual infrastructure budgets exceeding $2 million, and created structured career development programs that supported multiple promotions. I am passionate about reliable, automated, and well-governed engineering practices. I have driven the adoption of AI-assisted development tools with human-in-the-loop controls, quality guardrails, and review standards designed to protect production reliability. ## Skills 39 capabilities[Airflow](https://jobicy.com/talent/airflow.md)[Ansible](https://jobicy.com/talent/ansible.md)[Application Security](https://jobicy.com/talent/application-security.md)[Automation](https://jobicy.com/talent/automation.md)[AWS](https://jobicy.com/talent/aws.md)[Azure](https://jobicy.com/talent/azure.md)[BASH](https://jobicy.com/talent/bash.md)[Budget Management](https://jobicy.com/talent/budget-management.md)[Capacity Planning](https://jobicy.com/talent/capacity-planning.md)[Change Management](https://jobicy.com/talent/change-management.md)[Cloud Infrastructure](https://jobicy.com/talent/cloud-infrastructure.md)[Compliance](https://jobicy.com/talent/compliance.md)[Data Integrity](https://jobicy.com/talent/data-integrity.md)[Disaster Recovery](https://jobicy.com/talent/disaster-recovery.md)[Distributed Systems](https://jobicy.com/talent/distributed-systems.md)[Error Budgets](https://jobicy.com/talent/error-budgets.md)[GCP](https://jobicy.com/talent/gcp.md)[GDPR](https://jobicy.com/talent/gdpr.md)[GitOps](https://jobicy.com/talent/gitops.md)[Grafana](https://jobicy.com/talent/grafana.md)[Incident Response](https://jobicy.com/talent/incident-response.md)[Infrastructure as Code](https://jobicy.com/talent/infrastructure-as-code.md)[Kafka](https://jobicy.com/talent/kafka.md)[Kubernetes](https://jobicy.com/talent/kubernetes.md)[Linux Administration](https://jobicy.com/talent/linux-administration.md)[Mentoring](https://jobicy.com/talent/mentoring.md)[Observability](https://jobicy.com/talent/observability.md)[People Management](https://jobicy.com/talent/people-management.md)[Perl](https://jobicy.com/talent/perl.md)[PowerShell](https://jobicy.com/talent/powershell.md)[Prometheus](https://jobicy.com/talent/prometheus.md)[Python](https://jobicy.com/talent/python.md)[Root Cause Analysis](https://jobicy.com/talent/root-cause-analysis.md)[Site Reliability Engineering](https://jobicy.com/talent/site-reliability-engineering.md)[Spark](https://jobicy.com/talent/spark.md)[SQL](https://jobicy.com/talent/sql.md)[Team Leadership](https://jobicy.com/talent/team-leadership.md)[Terraform](https://jobicy.com/talent/terraform.md)[Virtualization](https://jobicy.com/talent/virtualization.md) ##
