Digital Marketing Expert Needed

Globex Digital's marketing module manages billions of ad impressions each month for the largest advertisers in Europe. Bringing many interesting challenges, such as "How could we promptly build freeform reports on 1B+ rows of statistics data?" And "How could we make a quick UI to create 100s of A/B tests?" We are looking for digital marketing exports/agencies to work with us remotely (Place doesn’t matter). We'll have a dedicated account manager to co-ordinate with you - whether you’re a freelancer, got a team, or if you run your own agency. Our accounts are huge clients from Europe - some major ecommerce companies, etc So there are a couple of pre-selection test assignments to be handled. We’ll just need one page answers to the questions based on 2 scenarios.
