About Me
Who am I?
Discover my story
Initially, I studied at Lodz University of Technology, but I quickly realized I needed more than just theory. I wanted to take action, so I left full-time studies and transferred to part-time at WSB Merito University in Poznań. This allowed me to fully dedicate myself to real projects while not giving up on formal education.
I took my first steps in the industry as an IT specialist at a bank, where I created my first real application. A desktop system for reporting errors by employees from different branches to the IT department. It was this project that sparked my true passion for programming. I started looking for my place, learning Java and Spring Boot, until I finally found NanoInflu. I joined as a Junior Developer and tackled an application based on Scala and Play Framework.
My commitment to the project quickly resulted in a promotion to CTO. In the meantime, I worked on projects for smaller clients, creating websites, landing pages, and e-commerce stores. Each of these projects was another step on my journey. All of this contributed to where I am now and where I'm heading in this beautiful world.
