What I'm looking for

I seek a hands-on BI role building impactful Tableau dashboards, collaborating with stakeholders, mentoring juniors, and solving data quality and performance challenges while advancing analytics capabilities.

I am a Tableau developer with 5+ years of experience delivering BI solutions using Tableau Desktop and Tableau Server, designing dashboards, writing complex SQL, and translating stakeholder requirements into actionable visualizations. I have implemented data blending, custom SQL, advanced geographic mapping, LOD calculations, YTD/MTD analytics, and performance tuning across enterprise databases including SQL Server, Oracle, PostgreSQL and Snowflake.

I take ownership of end-to-end BI delivery—requirement gathering, development, testing, publishing to Tableau Server, production support and end-user training—and have supported clients such as Inchcape UK, Siemens and J.C. Penney. I focus on producing clear, high-impact dashboards and metrics, mentoring teammates, and maintaining data quality and operational stability.
