At BT Group Plc, I architected and delivered 30+ governed data products using BigQuery, Dataflow, Dataproc, Cloud Composer/Airflow, and Terraform. I also optimized more than 100 BigQuery workloads, improving production query performance by up to 40%.
I designed an enterprise migration solution for 15+ TB of Oracle data to GCP, using automated validation and reconciliation to support production migration. I also developed reusable Terraform automation and a cross-project orchestration framework that reduced data-processing delays by approximately 50%.
At Tata Consultancy Services Limited, I engineered and supported enterprise data-warehouse solutions, including on-premises data migration to GCP and Oracle warehouse layers for ingestion, transformation, and reporting. I also contributed to ORION, a BT Group enterprise data-platform observability solution, and explored LLM-based approaches for DataOps analysis and root-cause investigation.
