Profile bio

About Andrzej Czajkun

I am a Regular Frontend Developer at LOT Polish Airlines. I develop and maintain web applications for the company's digital channels mainly using Angular with RxJs and NGRX libraries. I also collaborate with business owners and system analysts to identify and implement functional changes and optimizations in the existing solutions.Before joining LOT in June 2022, I graduated from both RWTH Aachen University and Wroclaw University of Technology in September 2020, with a double degree in Electrical Engineering, Information Technology and Computer Engineering. I have a strong background in electrical power engineering, which I applied in my previous job as an electrical engineer for two years. However, I decided to pursue my passion for programming and web development, and I taught myself the necessary skills and frameworks through online courses, projects, and internships. I am always open and excited to learn new things and challenge myself. I have lived in three different countries and learned three additional languages, Polish, English, and a little bit of German. I enjoy improving my programming and social skills, as well as learning psychology, in my leisure time. I also practice sports and mindfulness regularly to stay in shape both physically and mentally. "If you ask me something I don't know, I will say that I don't know yet, but I guarantee I will be able to find the answer."
