Mateusz Waszkiewicz

Senior Backend Developer

I once heard that 'Your team is as strong as its weakest link'. Working with my teammates at Codetain I thought to myself Man, do we have any weak link here at all? I like to think of us as a Team for Special Assignments. After 5 years in the tech industry, I ended up at Codetain. Thank goodness! I finally feel at home. Outside Codetain, I’m a football fan and player. I do a lot of running — training for mountain trail races. But I also like spending lazy evenings with video games.
