What I'm looking for

I seek a data-focused role where I can apply SQL, Excel and Power BI to drive measurable business outcomes, work collaboratively, and continue developing analytical and data engineering skills.

I am an enthusiastic data analyst with hands-on experience using Excel, Power BI and SQL to clean, transform and visualize data to inform sales and marketing strategies. I have demonstrated impact through projects and roles that increased reporting accuracy and boosted sales performance.

At Global Trust Consulting I improved sales report accuracy and efficiency by 35% through data cleaning and Power Query automation, and helped drive a 15% sales increase by delivering actionable Power BI dashboards. I also optimized SQL queries to speed data extraction by 30%.

My background includes sales analyst roles and a data analyst internship where I completed a KPMG AU data analytics simulation, developed relational databases and built predictive linear regression models for medical cost forecasting. I bring strong attention to detail, analytical problem-solving and a willingness to learn.
