17 years in #MagentaTeam

I have been with #Magentateam since the beginning of my professional career. It's almost 18 years. Everyday work in the IT & Tech area presents me with new challenges, and at the "end of the day" I always feel satisfied with a job well done. The team I work in is very well-coordinated and I can always count on the support and help of my colleagues. We do impossible things right away, for miracles you have to wait a while! Yes, T-Can!

2 years in #MagentaTeam

Our team is quite large, but very well coordinated. I especially appreciate the atmosphere we create. The work is never monotonous, there are new challenges and experiences, which always makes it interesting. I definitely like the opportunity to work hybrid (rather than on-site). In the case of B2B cooperation, settlements run very smoothly.
