Athi Mrasi

BI & Commercial Analytics Consultant · Johannesburg, ZA

I help e-commerce businesses improve tracking, reporting and profitability by turning sales, marketing and customer data into clear business decisions.

With over 9 years of experience in data analytics, business intelligence and performance reporting, I work with business owners, marketing teams and decision-makers who need better visibility into what is driving revenue, where performance is dropping and where profit may be leaking.

My work helps clients:

  • Improve GA4 and Google Tag Manager tracking
  • Build Power BI dashboards for sales, marketing and revenue performance
  • Understand customer behaviour and conversion journeys
  • Measure return on advertising spend and marketing effectiveness
  • Identify underperforming products, campaigns and channels
  • Track revenue, conversion rate, AOV and customer acquisition cost
  • Automate manual reporting and improve data accuracy
  • Turn complex data into practical growth and profitability insights

I combine technical analytics with commercial thinking. I do not only build dashboards or reports — I help clients understand what the data means, what is affecting business performance and what actions can improve results.

Available for remote, contract, consulting and project-based work in e-commerce analytics, business intelligence, marketing analytics and performance reporting.

My analytics philosophy

  • Decisions over dashboards

    A dashboard nobody opens is wallpaper. The goal is decisions and action.

  • Automate the boring

    If a report takes more than five minutes a week to update, automate it.

  • Honest numbers

    Validate the data before you visualise it. Distrust kills adoption.

  • Document everything

    If only one person understands the model, you don't have a system.
