  • Uncover revenue opportunities by analysing business data.
  • Find ways to reduce costs by spotting inefficiencies.
  • Improve customer value and satisfaction using data-driven strategies.
  • Help make better decisions using predictive models.
Measurement & Experimentation:
  • Develop ways to measure what really matters for your business.
  • Create custom metrics to track important business goals.
  • Use A/B testing to improve websites and digital products.
  • Run experiments to refine product features and user experience.
Business Intelligence & Tableau:

  • Set up data systems that make reporting simpler and more centralized.
  • Build tools that allow teams to access and understand data on their own.
  • Bring together different data sources to give a complete business picture.


My goal is to be a partner in your company's growth. I work on taking complex data and turning it into clear recommendations that drive real business results. Whether you're looking to increase sales, improve operations, or understand your customers better, I'm here to help you use data to achieve your goals.
