Delubac & Cie is a 100-year-old French private bank operating across 14 locations with a 201–500-person team, now in active technical debt remediation. The stack reveals a hybrid Java + Ruby on Rails architecture (Spring Boot, PostgreSQL, Docker, Kubernetes) supporting three core business lines: wealth management, corporate banking, and investment banking. Current project momentum centers on legacy system refactoring, CI/CD pipeline hardening, and a new digital banking product — suggesting a shift from monolithic banking platforms toward more modular infrastructure.
