[N. 02/03]How I work
How I work
What matters most is finishing the project — getting to the result. The path or the style doesn’t matter; what counts is the outcome.
That mindset goes back a while. I started building websites in a secondary school focused on IT, then kept working all through it — five years at a large German bank, beginning as a student IT-support intern and working up through systems administration and engineering into a Technical Product Manager role leading AI adoption.
In parallel, I studied Software Development, then Software Engineering & Big Data, at Unicorn University (2019–2025).
