Budzyński Maciej

Software Engineer - Python & Java Developer - Master of Computer Science


About Me

My name is Maciej Budzyński. I work as a Python Developer in the second largest pharmaceutical company in the world. I have a master's degree in computer science. I studied at the Catholic University of Lublin. In addition, I worked as a Junior Java Developer for COI, developing software that uses the whole country.

Backend programming is my specialty. I am not afraid to learn and use as much technology as I need. I adhere to the principle that a programming language is just a tool on the way to achieving goals. Personally, I feel good in Python writing web applications using FastAPI. I can also write in Java, Spring and Frontend.

Ringier Axel Springer Tech - As part of the Onet area, I took care of the development and maintenance of the e-mail product as a software engineer. For this purpose, I used tools such as Python, C, JavaScript, MySQL, Couchbase, Salt, Linux and AWS. Development and maintenance took place from server to pixel, which means that I was responsible for creating the functionality, testing it, implementing it on production linux servers and the AWS cloud, and then maintaining this functionality.
