I wrote some articles for ITProPortal.
My colleague and I had an interview with Twilio about using their API.
A group of 20 programming enthusiasts arrived at Netguru’s Poznan headquarters to improve their skills. I was their coach there, 8 hours a day, 2 weeks, every day. Such an amazing event! More info here.
I was a mentor for a group of 15-20 students during 2 months (~80h) of Ruby on Rails Workshops. Twice! This events took place in Katowice Institute of Information Technologies (April/May 2017 and February/March 2018). The info is unfotunately available in Polish only here and here.
I also write for Netguru blog. Just gotta scroll down here to see my recent posts.
