Strategy Development Marketing Social Media



Creating end-2-end data analytics solutions (dashboards as part of it) has been my daily business for more than 5 years, first in the Data Analytics team at the global consultancy firm Deloitte, now as a contractor who offers the same top-tier services.

Work history

Center for Sleep and Consciousness, University of Madison-Wisconsin
Research Specialist
I created and conducted experiments in sleep research, collected data, analyzed the data statistically, visualized my analyses and published my results in the scientific community in well-known journals.
Deloitte GER / UK
Senior Consultant, Data Analytics
I created Tableau and QlikView dashboards for reporting and sales insight management for big clients like Lloyds Bank, CYBG Bank, Vodafone RED, the NHS, Carillion, Thomas Cook and Deloitte Digital. I've also managed SQL databases of my clients.
Chief Data Whisperer
Did you know that every third marketer spends more than 50% of their time analyzing and managing data? That's time they are not using on actually marketing their e-commerce business! Give me a call and I can show you how to reduce that time to 10min.


Social Media Marketing & Retail Performance Analysis for an Online Cosmetics Retailer.

My e-commerce client had data flying around their social media marketing accounts as well as their sales performance accounts (FB, Instagram, and Google Ads, Shopify, Amazon Seller Central, and Klaviyo). I sourced all of that into a new database and attached management dashboards.

Reporting Strategy for a Private School

I created insights dashboards in Tableau for a big international school. They were just starting with actionable dashboard reporting and a lot of their data still came from various software sources. It was a challenge integrating all of it into various data models for all their departments.
