Hi, my name is Bartosz Krajka.

I’m a brutally agile full-stack web developer.


On the backend, I prefer Ruby on Rails, but don’t mind Node, NestJS, TypeScript.

On the frontend, I prefer React.js, but don’t mind vanilla JS.

In terms of infrastructure, I prefer AWS, but don’t mind GCP, Azure, even bare metal.

Software craftsmanship

I particularly specialize in:

  • agile (delivering in iterations)
  • automated tests
  • professional communication

But the list goes on:

  • clean code
  • code review
  • pair programming
  • knowledge sharing – see Read more page
  • communication with business
  • problem-solving
  • proactivity


My interests outside IT include:

I love spending a lot of money on books. On the hobby level, I like oldies, NFL, and board games.
