Solution Design & Data Model Specification
Requirements Translation: Partner with the product owner to translate ambiguous business questions into structured technical visualizations.
Data Spec Blueprinting: Design and document the required data model specifications (grain, joins, aggregations) needed to power dashboards, passing clear requirements to the Data Engineering team.
Prototyping: Build rapid wireframes and mockups to align stakeholder expectations before full-scale development.
E2E Dashboard Development & Performance Tuning
Advanced Visualisation: Build scalable, clean, and intuitive Tableau dashboards that adhere to modern UI/UX design standards and executive-level reporting requirements.
Performance Optimisation: Architect dashboards utilizing Tableau best practices (Extract vs. Live optimization, efficient calculated fields, minimized LOD expressions, and proper indexing backgrounders) to ensure sub-second rendering times on massive datasets.
SQL Data Validation
- Independent QA: Conduct rigorous validation testing by cross-referencing Tableau dashboard logic against database records using SQL to guarantee absolute mathematical accuracy before release.
Environment Strategy & Release Management
Deployment Governance: Execute a structured multi-environment strategy (Development ➔ Staging ➔ Production).
Version Control: Ensure workbook configurations, data source connections, and parameter definitions swap cleanly across environments without manual hardcoding or post-deployment breaking changes.
User Acceptance Testing (UAT): Lead UAT sessions with structured test scripts to secure final validation signs-off from business users

Key Technical Qualifications
Tableau Mastery: Expert-level proficiency with Tableau Desktop, Tableau Cloud/Server, and Tableau Prep. Deep understanding of row-level security (RLS), advanced parameter actions, and dynamic dashboard switching.

Data Modeling Knowledge: Strong foundational understanding of data warehousing concepts, including Star/Snowflake schemas, dimensional modeling, and managing point-in-time snapshot data.
Environment Management: Proven experience managing Tableau sites, project structures, folder permissions, and workbook publishing cycles across enterprise-grade Dev/Prod pipelines.
