Apprenticeship at Siemens
Four years, four departments: from software development and supporting apprentices to process automation and first-level support. Each year brought new responsibilities and a new team.
Internship in Ireland
First line support in an English-speaking team: real requests through Zendesk, direct contact with users and plenty of new experiences in an unfamiliar work environment.
What drives me
I have been interested in how technology and software work since my school days. Today, I develop applications, support users in production and learn something new with every project.
Personal projects
Learning by building.
Alongside my work, I build personal IT projects to try new technologies directly and deepen my knowledge. This is how new ideas gradually become working applications.
