ZenSkayl Workforce OS: Modular HR & Payroll Platform

I designed and built ZenSkayl Workforce OS on my own, from product design and architecture to development and deployment.

The problem: small businesses run leave, attendance and payroll on spreadsheets and WhatsApp, because proper HR software is priced and built for large companies.

The solution: a modular HR platform where businesses start with Core and switch on only the modules they need, paying only for what’s active.

What I built: • 16 add-on modules, including leave, shifts, time tracking, payroll, approvals, performance and hiring • Role-based access control and a full audit trail • Payroll with a safe “Try it” preview before any change goes live • An AI assistant that works with company data without storing it or training on it • An employee mobile app • GDPR-compliant hosting in Frankfurt, Germany

My role: product owner, designer and sole developer.
