Tableau Experience:
I have extensive experience designing, building, and optimizing Tableau dashboards that transform raw data into actionable insights. My work has included connecting Tableau to a variety of data sources—such as PostgreSQL, SQL Server, and cloud-based platforms—then modeling and preparing data to support reporting needs. I focus heavily on usability and performance, ensuring dashboards not only provide accurate analysis but are also intuitive for end-users.

Key highlights of my Tableau work include:

Interactive Dashboards: Designed and developed dashboards with filters, parameters, and calculated fields that allow business users to explore data dynamically.

Data Preparation: Used Tableau Prep and custom SQL queries to clean, join, and aggregate data for analysis.

Performance Optimization: Applied best practices such as extract creation, aggregation, and dashboard design techniques to reduce load times and improve performance.

Storytelling with Data: Built dashboards that not only report KPIs but also highlight trends, anomalies, and actionable insights for leadership decision-making.

Collaboration & Governance: Worked closely with business stakeholders to translate requirements into visuals, and established standards for version control, publishing, and permissions on Tableau Server/Cloud.

Consulting Experience: Managed multiple clients/projects at once, balancing competing priorities by developing scalable templates, reusable data sources, and consistent design frameworks.
