Über Kaja
I build, fix, and stabilise HR functions — in organisations that are growing fast, going through acquisition, or simply need HR that actually works.
15+ years leading HR in regulated, unionised, and multi-entity environments across Germany and Central Europe. I work at board level and get my hands dirty. Both matter.
What I deliver:
— HR build-up from scratch (60 → 400 employees)
— Post-acquisition integration across multi-entity structures (650+ workforce)
— Compliance restoration in fragmented, high-risk environments
— Payroll accuracy to 99%, sickness absence −35%, turnover −15%
— HRIS implementation and full payroll digitalisation
— HR systems consolidation across multiple teams
— Labour law, works councils, union negotiations (Germany & EU)
Languages: German (native) · Polish (native) · English (C1) · Italian (learning)
