Message

At Advance Business Computing, I led Big Data, Databricks/Cloudera Lakehouse, and Securonix SIEM/SOC platform work for Ooredoo, across on-premise and cloud environments. I designed streaming pipelines with Airflow, Spark, Kafka, and Flink, and managed Apache Iceberg Bronze/Silver/Gold tables.

For Ooredoo, I delivered the end-to-end Securonix SIEM implementation and integrated it with Cortex XSOAR, EDR, threat-intelligence platforms, CAPAM, and DAM. I also administered Cloudera CDP platforms and built Grafana observability dashboards.

At Transguard LLC, I delivered Securonix SIEM and Cloudera CDP platform work for Dubai Airports’ critical-infrastructure environment. I architected Kafka/Confluent streaming pipelines and integrated threat intelligence, SOAR, and EDR capabilities.

Across projects for DEWA and Etisalat, I delivered data hubs and Lakehouse platforms, including AWS- and Azure-based pipelines. Earlier, I built an audience measurement analytics system at Infosys and developed the Maglis Big Data system and an in-house SMB ERP application at Tata Consultancy Services.
