Poland · 8 years of experience · Upper-Intermediate ·Published yesterday · In passive search
I'm looking for a software engineering role as a senior back-end and/or data engineer.
I began my career as a Python back-end engineer, working on both startup and enterprise projects.
About 3 years ago, I decided to transition into data engineering, and a year later, I obtained the certificate of a Google Cloud Certified Professional Data Engineer.
In addition to my primary job responsibilities, I also have experience teaching Python, including conducting lessons and evaluating homework, as well as mentoring fellow engineers.
I'm open to switching to other programming languages besides Python as well since each language is just a tool for solving a particular problem in the first place.
I'm ready to work either independently or in a team of professionals (of course, the latter option is preferred).
