About
Senior independent consultant in Business Intelligence & Commercial Analytics.

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.
