Freelancer profile translated to English.

Description

I develop automation solutions and custom software that solve real problems – not on paper, but in practice.

What sets me apart: I have already measurably advanced two large corporations, including a market leader in its industry and one of the largest employers worldwide, through tailor-made solutions. My projects are in international use and recognized worldwide.

I now bring this corporate quality directly to you – whether it's workflow automation, custom tools, API integrations, data processing, or web scraping.

You describe your problem to me – I deliver the solution. Lean, robust, and tailored directly to your needs.
