What I'm looking for

I want to keep building predictive models, automated dashboards, and clean, validated data pipelines that turn into clear stakeholder decisions and better forecasting.

I support stakeholders at DBSAutos as a data analyst, collaborating with data engineers to maintain and build data pipelines for cross-functional efficiency.

I led projects aimed at improving customer retention and sales productivity, and I create analytic reports that help stakeholders and group heads make actionable decisions.

I designed predictive statistical models that improved forecasting accuracy by 15%, and I built automated Power BI dashboards to keep KPI reporting timely. I’ve also streamlined data validation and delivery to reduce data error rates.

Before that, I handled data entry at MetroeyeSecurityCompany, verifying source documents and correcting inconsistencies while maintaining accurate records and improving data access times. I also completed analytic reporting for stakeholders and handled sensitive information with discretion.
