Analyst. Storyteller.
Problem Solver.

I'm a data analyst with a passion for the business, tech and finance industries. I believe data is only valuable when it drives decisions — so every analysis I produce comes with a clear narrative, actionable insights, and visuals that non-technical stakeholders can actually use.

My toolkit spans the full analytics workflow: from Power queries and Excel financial models and Power BI dashboards. I'm equally comfortable digging into a messy dataset with SQL and presenting findings to a boardroom.
