What I'm looking for

I'm looking for a role where I can apply my data analysis expertise to solve real business problems, collaborate with cross-functional teams, and contribute to meaningful, data-driven decision-making

I am a results-driven data analyst with over 15 years of experience in transforming raw data into actionable insights. My expertise lies in data integrity, process automation, and enterprise reporting, utilizing tools such as SQL, Power BI, Palantir Foundry, and Excel. I have a proven track record of building scalable solutions that drive significant business impact.

In my current role at AT&T, I serve as a Subject Matter Expert across national infrastructure programs, where I have streamlined analytics and reporting processes. My efforts in automating lifecycle tracking tools have improved project visibility by 40%. I have developed SQL queries and Excel dashboards to monitor performance, ensuring standardized data across sources for consistent reporting.

Throughout my career, I have held various roles that have honed my skills in data analysis and project management. From resolving data inconsistencies as a Data Integrity Specialist to leading national project tracking tool development as a Senior Technical Project Manager, I have consistently delivered results that align with business goals. I thrive in collaborative environments and am passionate about leveraging data to drive strategic decisions.
