Lead Tableau Developer & Consultant

Categories

Work Experience : 2018-2021

Leading Tableau vision to set out the product direction and manage the development team. The project involved creating stricture for the business, which helped to understand how 3 business reporting data can be merged into one, and have the same reporting platform across the entire company after Hotelbeds merged with the other two businesses. Creating new advanced reporting features and overhauling old reports from Cognos, Qlikview, and PowerBi tools. Data was extracted from multiple source systems and moved to a single data warehouse which was later used to create reports for different departments. This was achieved after close collaboration with
company leaders and department stakeholders. Some data processes required automation, which involved Alteryx and Tableau Prep tools to be used to capture data. The mission was to have a data-driven organization that also involved training over 2000 users across 10 departments on how to create and interact with reports on Tableau Online/Desktop. The training process included creating customized online courses, running webinars, and on-site classes for different levels of users using best practices which also led to creating new standards and governance rules.
