What I'm looking for

I’m looking for a role where I build Power BI dashboards, write SQL for reliable insights, and collaborate with stakeholders—using analytics (and AI-driven thinking) to improve operations and customer outcomes.

I’m a results-driven Data Analyst focused on turning raw data into clear, actionable insights. I deliver accurate reporting, streamline dashboards, and support better decision-making across fintech, hospitality, and legal environments.

In my roles, I’ve trained participants on Excel, SQL, and Power BI, built interactive KPI dashboards, and developed SQL queries to reduce report preparation time. I also apply data-driven analysis to improve customer service response, retention, productivity, and data integrity—while building strong datasets and learning materials that make results repeatable.
