What I'm looking for

I am seeking BI/Tableau roles where I can design scalable analytics, consolidate reporting, mentor teams, work with cloud data platforms, and deliver executive-level dashboards in an agile, collaborative environment.

I am a Senior BI and Tableau developer with 18+ years in IT, specializing in data warehousing, BI solutions and dashboarding across Banking, Financial, Retail and Automotive domains. I hold Tableau Desktop Specialist certification and have extensive hands-on experience with Tableau Desktop, Server, Prep, Business Objects and multiple databases.

I've led end-to-end analytics projects: consolidating fragmented Snowflake/Salesforce reporting into scalable base-table driven models, building executive-level dashboards from high-volume datasets (500M+ rows), and improving Tableau performance and maintainability. I regularly coordinate with stakeholders, data engineering and QA while managing deployments, permissions and support in Tableau Server.

I bring strong SQL and data-modelling skills, experience with cloud data platforms (Snowflake, Redshift, BigQuery, Azure Databricks), ETL tools (Informatica, SSIS) and BI tooling (Alteryx, BO, OBIEE). I thrive in Agile/DevOps environments, mentor juniors, and focus on delivering actionable, well-designed visual analytics that drive business decisions.
