About Me

My name is Tomasz Czajęcki (tom-ash cha-yen-ski). I am an engineering manager in Expo. I am originally from Kraków, Poland and currently live in Helsinki, Finland. Reach out on X or Bluesky if you are around!

Short bio

I write most of my code in TypeScript and I am a big fan of the React ecosystem. I am most experienced as a frontend developer, but I worked on pretty much anything from designing screens in Figma, through frontend, backend and database or infrastructure work.

I worked in Software Mansion between July 2017 and March 2020. For Rainbow Wallet in 2022 Feb – Oct. In Expo since December 2022.

As far as my hobbies go, I started my journey with programming because of games and it still brings me disproportionate amount of joy to code things that vaguely resemble gamedev problems. This is what this blog is mostly about.

I have done my master’s in a double degree program in cybersecurity program called SECCLO in Aalto University in Helsinki, Finland and KTH in Stockholm, Sweden.
