Data & Analytics professional turning complex datasets into reliable dashboards and actionable business decisions.
What I'm looking for
I’m a results-driven Data and Analytics professional with experience turning large, complex datasets into clear insights, reliable dashboards, and actionable recommendations. I’ve built and maintained KPI dashboards in Excel to track error rates, output volumes, and turnaround times, and I translate complex outputs into narratives that both technical and non-technical stakeholders can use.
Across my roles, I’ve owned data quality validation and governance across operational reporting workflows, serving as an escalation point for data discrepancies and improving metric definitions to prevent recurrence. I implement automated data validation and quality-check workflows to surface anomalies early, reduce downstream reporting errors, and eliminate manual rework—supported by SQL (MySQL), Python (pandas), and BI tools like Tableau and Power BI, plus a hands-on portfolio of SQL cleaning and dashboard work on real datasets.
