What I'm looking for

I am looking for a role that challenges my analytical skills and fosters growth.

I am a dedicated Tableau Developer with a strong background in data visualization and analysis. At Better Collective, I redesigned and deployed over 40 interactive Tableau dashboards, significantly enhancing data visualization for multiple departments. My efforts led to a remarkable increase in dashboard adoption and improved decision-making processes across the organization.

Prior to my current role, I served as a Data Analyst, where I collaborated with Operations and Data Engineering teams to ensure data accuracy and integrity in critical reports. My proficiency in SQL and Tableau allowed me to identify key performance trends and customer pain points, driving operational improvements and enhancing customer retention. I am passionate about sharing knowledge and fostering a collaborative learning environment, which I achieved by conducting informal training sessions for my teammates.
