BB Agency is a 51–200-person digital agency based in Croatia, founded in 2013, serving mid-market and enterprise SaaS companies. The tech stack reveals a shift from legacy monoliths toward modern cloud-native architecture: Java/Spring Boot on AWS with PostgreSQL, Kafka, and React frontends, now actively replacing Oracle HCM Cloud. The active project list—HR/payroll platform, microservices integration, zero-trust architecture, data migration—paired with pain-points around legacy system replacement and compliance, signals BB Agency is moving from traditional agency services into platform-scale product engineering for the HR/payroll domain.
