Mite Mitreski

My name is Mite Mitreski. I live in Stockholm, Sweden with my wife and son. Welcome to my personal website and blog! 


I work as a CTO for Signicat developing high trust services powering fintech and goverments across europe and worldwide. Prviously I was an engineering director in Stockholm, working for Klarna to make smooth buying products and level up the customer experience for both our merchant and our direct customers. 

Working together with outstanding teams, I have been building Klarna Checkout, Klarna Payments, Merchant Card Services, and helping grow and establish all other purchase products such as In-store or Onsite messaging. In my different hat at Klarna, I help develop the engineering culture by being involved in how our opens source program works, our events we organize internally and externally, and work with the marketing and publications we participate in as Klarna engineering.

Before moving to Sweden, I ran Java User Group Macedonia (JugMK), building the community and developing the event scene. The first book that I co-authored is called HTML 5 Data and Services Cookbook . I tend to have varied interests, so I was a lecturer for programming courses for a while. Sometimes I speak at conferences and universities about topics I work with and find interesting. If you have some interesting topics you think I would be good to talk about, reach out. While back in Macedonia, I was involved in local software communities like hacklab KIKA and the Macedonian section of IEEE.


I love spending time with my wife and kid it's been game changer since Martin was born for both of us.

When I get some time to myself, I get in a few hours of gaming, reading, and trying to produce content. I have bounced between hobbies for quite some time. Recently I have been spending a lot of time cooking and leveling up my chef game, writing a bit, on and off I try to do some photography and put out some in the public
