What I'm looking for

I'm seeking a Data Analyst role in Scotland where analytical rigour supports business decisions.

At Mater Dei Hospital, I designed and maintained Excel dashboards that helped management reduce monthly budget variances by 12%. I also cleaned and validated more than 5,000 financial transaction records, achieving 99.5% data accuracy.

I traced recurring data inconsistencies to their root causes and implemented corrective measures, reducing repeat errors by 25%. By streamlining accounts receivable workflows with VLOOKUP and PivotTables, I cut manual processing time by 15%.

As a Data Analyst Intern at Total Energies Plant, I analysed historical sales data to forecast quarterly demand, improving inventory planning accuracy by 18%. I also built and back-tested predictive models that reduced forecasting error margins by 10%.

I'm continuing to build a sales forecasting model using Python, Pandas, and ARIMA to predict three-month retail sales trends. I hold a BSc Honours in Operations Research and Statistics and an IABAC Certified Data Scientist credential.
