At Renewable Parts Limited, I design Power BI reporting solutions that bring sales, procurement, inventory, warehouse, and refurbishment data together. My dashboards support operational visibility and executive decision-making, while reporting automation has reduced manual effort by 40%.

At Amdari, I delivered business intelligence solutions for clients across multiple industries. I implemented Power BI, SQL, and Tableau dashboards that increased self-service reporting adoption by 35% and reduced reporting turnaround by 40%.

At Tunnex Laboratories, I led the migration of more than 10 million records from Oracle into modern reporting environments, reducing data management costs by 20%. I also developed automated ETL pipelines and dashboards for procurement, inventory, supply chain, and laboratory operations.

At Lloyds Banking Group, I used SQL analysis to identify fraud patterns and reduce false-positive investigations by 25%. Earlier, at Tesco Mobile, I developed churn analysis and customer reporting that informed retention initiatives and contributed to a 15% reduction in customer churn.
