Experience
Hands-on reliability work in high-stakes production environments.
- Primary on-call responder for mission-critical payment platforms serving 700+ million users.
- Built and operated a multi-region active-active MySQL cluster across Azure and two on-prem data centers for high availability and disaster recovery.
- Engineered NGINX load-balancing strategies and optimized SQL performance through query profiling and execution plan analysis, reducing p99 latency by 35%.
- Centralized database replication monitoring with ELK, Grafana, and Prometheus, reducing root-cause analysis time by 70%.
- Monitored YARN ResourceManager and Kubernetes cluster health, optimizing allocation, resolving pending pods, and terminating rogue processes.
- Built and maintained Docker and Podman containers with GitLab CI/CD and Harbor for repeatable image builds and production release consistency.
- Automated platform health checks, recovery workflows, and incident response with Python and Bash, reducing manual operational effort by 60%.
- Built Grafana dashboards on top of Prometheus monitoring to improve SLA/SLO tracking and reduce MTTR by 60% across big data services.
- Defined and tracked SLOs and error budgets across owned services, using PagerDuty for alerting and escalation.
- Conducted manual chaos and failure-injection testing on staging infrastructure before production rollout.
- Supported 24x7 production operations for Visa's 450 PB Hadoop ecosystem, including HDFS, Hive, and Presto.
- Automated AWS infrastructure provisioning and configuration management using Terraform and Ansible, reducing provisioning time by 70%.
- Optimized Apache Airflow DAG scheduling and dependency management, improving workflow success rates from 88% to 96% across 500+ daily production pipelines.
- Monitored YARN ResourceManager queue-level allocation for Spark jobs and managed Kubernetes cluster health.
- Automated platform health checks, recovery workflows, and incident response using Python and Bash, reducing manual operational effort by 60%.
- Managed Control-M batch scheduling and CRON jobs, proactively resolving dependency failures and SLA breaches.
- Deployed a ServiceNow-integrated L1 support chatbot backed by OpenAI models and historical ServiceNow, Confluence, Jira, and SOP data.
- Troubleshot Kerberos authentication, LDAP integration, and IAM policies across the Hadoop ecosystem.
