BPS is Uruguay's national social security institution — one of the largest and most complex public systems in the country, managing sensitive data for millions of citizens under strict regulatory and security requirements. This wasn't a fintech engagement, but the environment shared the same characteristics: legacy infrastructure, high data volumes, zero tolerance for disruption.

Kreitech collaborated on a large-scale modernization program, migrating legacy Java systems to microservices architecture and Angular on the frontend. The work included database migrations, system integrations, QA automation, and team training — all executed incrementally to preserve operational continuity throughout the process.
