For about three years I have worked daily with data that is messy, constantly changing and still has to be processed reliably. That turned into a working method: keep records clean and current, find inconsistencies before anyone notices them, and replace the same manual steps with verifiable automation — measure before claiming anything, and rebuild when the measurement comes back bad. Data maintenance is an ongoing task full of repetition; I do it carefully and at the same time see what can be automated.

About me
I orchestrate AI. I take responsibility for the result.
My path began with a clear signal: after my degree in Economic Cybernetics (bachelor level recognised by the German ZAB), I took 1st place among around 6,000 participants in the RS School / EPAM JS/FE Pre-School course in 2022.
Since then I have spent about three years working daily on web and data automation — AI-assisted: I define the workflows, implement them, verify the results and systematically look for root causes when something is off.
Today I focus that experience on data maintenance and digitalisation: keeping records clean and current, finding inconsistencies before anyone notices them, and replacing the same manual steps with verifiable automation.
