What I'm looking for

I’m looking for a role where I can turn complex data into clear insights, build Power BI dashboards and reports, and automate workflows—while also supporting executives with efficient virtual and administrative assistance to improve productivity and business performance.

I’m a results-driven Data Analyst and Virtual Assistant with expertise in data analytics, business intelligence, automation, and administrative support. I turn raw data into actionable insights that strengthen strategic decision-making and operational efficiency.

In my recent roles at Globaltech, I’ve analyzed complex datasets, built interactive dashboards with Power BI, and performed data cleaning, transformation, and modeling to improve accuracy and reliability. I also support executives with calendar management, reporting, and professional presentations for stakeholders.

I pride myself on delivering clear, accurate reporting and efficient workflows—such as improving decision accuracy by 45% with data-driven reporting systems and reducing reporting time by 60% through automated dashboards. I’m now focused on continuing to help teams monitor KPIs, discover trends, reduce errors through validation, and execute digital transformation using data.
