About Me

My name is Tomasz Czajęcki. I am an engineering manager in Expo. I am originally from Kraków, Poland and currently live in Helsinki, Finland. Reach out on X 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 also love Zig language and in my free time I like to play with graphics programming (OpenGL, WebGPU etc.). I code for a living since 2015.

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

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