I’m a Data & Business Intelligence Analyst with a degree in Statistics, focused on helping businesses understand their data and make decisions they can actually act on.
I work across the full analytics workflow, from asking the right business questions and querying data in SQL, to building dashboards in Power BI and Tableau, and to delivering reports that show what’s working, what needs attention, and where businesses can improve and grow.
My background in Statistics means I don't just build visuals, I ask the right questions first; What does this number actually mean? What's causing this trend? What should we do about it?
Take a look at my projects to see how I turn raw data into business insights and actionable recommendations.

Excel
A B2B CRM and sales pipeline dashboard that covers where deals are won and lost, which industries, markets, and organization sizes drive the most revenue, and which sales reps convert at the highest rate.
