ABOUT ME
I connect business priorities with evidence people can act on.
I’m a Business Data Analyst and PMP who helps organisations turn complex data into clear business decisions. I begin with the objective, stakeholders and operating context, then build a practical path from raw information to validated insight.
My work covers data-quality auditing, SQL analysis, Python, Excel, Tableau, Power BI, KPI development and stakeholder reporting. I explain assumptions, limitations and business implications clearly, so clients understand not only what changed, but what to do next.
Whether the goal is stronger performance visibility, more reliable reporting, risk identification or a dashboard teams can use with confidence, I keep the work focused on the decision behind the request.
