Case studies

Named case studies from insurance, banking, public administration, financial regulation, and retail, focused on responsibilities, technical contribution, outcomes, and clear confidentiality boundaries.

Some projects were delivered as part of client engagements through Babel. These case studies cover publicly shareable responsibilities, technical contributions, and outcomes without exposing confidential architecture, source code, business data, security mechanisms, or internal client information.

Featured case studies

Insurance

Insurance · frontend architecture modernization

Modernizing an Insurance Customer Portal with Micro-Frontends and 90% Test Coverage
