What I'm looking for

I’m looking for a senior/lead BI role where I can build and govern high-performance Tableau dashboards, optimize Snowflake SQL pipelines, and guide teams to deliver trusted, data-driven insights for global stakeholders.

I’m a Lead & Senior Tableau Developer with 14+ years of IT experience and 8+ years in Business Intelligence and Data Analytics. I build scalable data warehouse solutions, create high-performance Tableau dashboards, and optimize SQL and Snowflake pipelines to turn data into decisions.

I lead end-to-end Tableau BI delivery aligned with business objectives across multiple domains, and I’m comfortable owning stakeholder collaboration from discovery through rollout. I’ve managed and mentored a team of 6 Tableau developers and analysts, while implementing data governance and security practices that improve adoption and trust.

On the technical side, I design dashboards with advanced calculations, LOD expressions, parameters, sets, and data blending, and I tune performance through query tuning, efficient extracts, and visualization best practices. I also work with Snowflake features (Virtual Warehouses, Streams, Tasks, Snowpipe) plus robust data modeling (Star & Snowflake Schemas) to keep analytics reliable and scalable.

My work has supported enterprise dashboards used by 50+ stakeholders across business units, improving dashboard load times by 30–50% and overall data processing performance by up to 40%. I bring a quality-first mindset—data profiling, validation, and quality assurance—so insights stay accurate, consistent, and actionable.
