You can get a work certificate of every individual work task or you can create WorkPilots-CV and gather all the tasks there. (There is an article about creating CV:https://workpilots.zendesk.com/hc/en-us/articles/360000390272-CV).
This way you can get a certificate of an individual work task:
Open the History-page of your profile ("Orders" on the left side bar of the page -> and History-tab on that page). Select the task, where you would like to get that certifcate from. Then, there on the right edge of the page, is a button "Get certificate". (On the left side of that same row is the status of that task.)
By clicking that a pop-up window opens up where you can choose, do you want to get the feedback of that task on the certificate or not.
Then just click "Download certificate", then that certificate downloads and you can save it to your computer.
If that version is not enough and you need some kind of other work certificate, send us an e-mail to firstname.lastname@example.org and we will look at it then.
