What I'm looking for

I seek roles where I can design governed, self-serve analytics and dashboards that empower stakeholders, mentor teams, and deliver measurable business impact.

I am a Data Visualization Developer with deep expertise in Tableau, Excel, SQL and a strong background in building actionable dashboards that drive decision-making and process optimization.

Across roles in fintech, healthcare, marketplace and analytics consultancies, I have led dashboard migrations, team delivery, and self-serve reporting initiatives that reduced manual reporting, improved observability and increased client engagement.

I have delivered measurable outcomes such as improved patient data management, increased client engagement, higher report accuracy and faster report generation by redesigning dashboards, implementing governance and standardizing visualization best practices.

I am passionate about enabling stakeholders to independently monitor performance through intuitive, governed analytics environments and enjoy mentoring others in data visualization and analytics best practices.
