At Visa, I architect, build, and operate cybersecurity telemetry platforms spanning approximately 10 PB across 350+ servers, six clusters, and three data centers. I manage roughly 80 security datasets and production analytics workloads sourced from QRadar, Splunk, cloud platforms, and enterprise systems.

I lead end-to-end batch and streaming pipelines using syslog-ng, Kafka, Spark, HDFS, Apache Druid, Airflow, and Elastic Stack. I modernized a licensed Greenplum platform to Apache Druid, partnered on migrating 40+ datasets, and supported 300–400 TB of annual ingestion and approximately 900 million records per day across four regions.

Previously at Swift Solutions, I administered a 250+ node Hadoop cluster and more than 300 Linux servers, building high-volume ingestion and transformation pipelines with Kafka, Flume, Spark Streaming, Scala, and Sqoop. At IBM, I supported Hadoop production environments and migrated enterprise data from DB2 and flat files into HDFS.

I focus on resilient, secure operations: zero-downtime maintenance, capacity planning, cluster expansion, performance tuning, security remediation, automation, and production readiness. I work closely with cybersecurity, SIEM, data science, platform, compute, and identity teams to solve complex infrastructure and analytics problems.
