What I'm looking for

I'm looking for data analyst opportunities where I can turn complex datasets into clear dashboards and actionable business insights, collaborate with technical and non-technical stakeholders, and continue growing in SQL, Python, visualization, and statistical analysis.

I've analyzed sales data at BarleyGate Limited and built dashboards across regions, sales channels, customer segments, and product categories to identify top-performing products and cross-selling opportunities.

My Olist e-commerce project examined 100,000+ Brazilian orders using MySQL, Python, Excel, Tableau, and GitHub. I designed an eight-dataset ER diagram, wrote 15+ SQL queries, and created interactive dashboards covering revenue, customer behavior, seller performance, delivery, and satisfaction. My Microbiology background also brings a rigorous approach to data quality, statistical analysis, and evidence-based reporting.
