Humanitas

Humanitas is a sophisticated <strong>multi-tenant SaaS platform</strong> designed for the unique needs of the enterprise market, including full compliance with complex payroll, tax, and HR regulations. The system serves <strong>200,000+ user profiles</strong> across dozens of independent tenants each fully isolated using a <strong>database-per-tenant architecture</strong>.

Handling 200,000+ users demanded a database strategy that guaranteed <strong>100% cross-tenant data isolation</strong> while maintaining high-speed performance across complex <strong>multi-currency financial calculations</strong> and pension (PF/ESS) logic.

Implemented a dynamic <strong>"Database-per-Tenant" architecture</strong> using <strong>NestJS and PostgreSQL</strong>. A <strong>cursor-based streaming pagination engine</strong> on the React frontend turns heavy financial queries into buttery-smooth infinite scrolls with zero memory overhead.
