Reading Time: 7 minutes

Here we go again.
This is the second episode of our docuseries about how we are managing retailers’ data for our beloved customers.

With this part, we would like to introduce the hidden aspect of our product and I promise, it is not a buzzword: Machine Learning.
In the following paragraphs, we are going to show new technical improvements and the analytics aspects under the hood.

In Everli we have recurring internal moments that we use for sharing knowledge.

In the next paragraphs, I will show you the evolutions of this process during the years.

Covid-19 changed and is changing everything.
From customer behaviour to customer spend, no one could have expected this.
Our servers neither.
This post would like to be a simple overview of what we did to maintain our website and apps reliable during this time.
And yes, you have read properly, how we kept the infrastructure responsive while serving more than 4000% new users (and of course the previous one) plus a few DoS attacks.
