I have transferred to the web services team. I have the pleasure to work with modern microservice architecture and a variety of specialists – from DevOps engineers to UX designers.

My daily work involves developing front-end services based on JavaScript (React, Next.js) and GraphQL. However, I also regularly develop back-end services in TypeScript (NestJS), Go and GraphQL.

I independently plan small projects that take about 300 hours to complete. Half of my professional communication is in English.

I worked in a team integrating the company’s software with that of business clients. The integration was done using Android API (Java) and C++ libraries. Furthermore, I developed products based on the same technologies and created developer tools in JavaScript and Python.

My role, besides technical skills, required daily communication with clients in English. Its purpose was to define requirements and solve ongoing problems.

June 2019 – December 2019

I helped develop cryptographic libraries and servers (C++) and applications dependent on them (Java + JNI, QT). I configured a reporting system using SQL queries. I prepared Docker images and Linux packages to deploy applications on client machines.

Biography

I won a lottery

I was lucky to be born in 1998 in Toruń.

If it had happened 20 years earlier, as a child I wouldn’t have had the tools to learn programming on my own – the most basic one is a computer. In 1990, when I would have been 12, the price of a computer was 18.31 of the average monthly salary. In 2010, when I was actually 12, that price had dropped to only 0.75 of the average monthly salary. I don’t want to write off my hypothetical career too early, so let’s say that little Bartek would have been a natural entrepreneur. He would have earned the money for his first computer by cutting the grass since he was able to reach the handle of a lawnmower.

Even then, a computer wouldn’t be useful to me if I had nothing to run on it. My favorite childhood game – Rayman 2 – which made me interested in game development and later in programming, was released in 1999. Baltie educational programs that I used to create the second series of my games (about the first one in a moment), arrived in Poland in 2001. I don’t rule out that their older, less friendly counterparts could also inspire me to become a programmer. They had to inspire someone – otherwise Rayman 2 and Baltie would never have been made. However, even in 2010, I had to be determined to turn the enthusiasm of the novice into the skills of an expert. I don’t think I would have been determined enough to overcome the barriers I would have faced 20 years earlier. I would have chosen a different, more approachable profession. I always thought I would have become a doctor. Or a carpenter.

Perhaps I would become interested in computers again in adulthood, but I wouldn’t change my studies or career for a field I know nothing about. At best, it could be my hobby that I would spend a couple of hours a week on between work and children. But that’s a minor inconvenience, considering that 40 years earlier I might not have been born at all.

The arrangement of blood types in my family put me at risk of developing hemolytic disease of the newborn, in which the mother’s immune system attacks the baby’s blood. Mothers have no influence over this – blood types are a lottery and a ticket that the child draws is at times unfortunate. Fortunately, this disease is practically eradicated in developed countries. The drug that prevents it successfully passed clinical trials and was approved in the 1960s – a decade after my hypothetical birth. This reminds me that my way of life and security that comes with it have existed only recently. And unfortunately, not everywhere.
