  • Modernizing a Global Credit Bureau with 99.97% Application Availability and Zero Disruption

    Modernizing a Global Credit Bureau with 99.97% Application Availability and Zero Disruption

Client

A leading global credit bureau headquartered in the United States, the client operates across 24+ countries spanning North America, Latin America, and Europe. It offers advanced credit risk assessment and identity solutions such as credit scoring, fraud detection, and identity verification to both individuals and businesses.

Renowned for its data analytics strength and strategic acquisitions, the organization is critical in enabling responsible lending. Its platforms support a broad spectrum of financial players, from traditional banks and credit unions to fintechs and digital-first subprime lenders that rely on fully online channels to serve high-risk or underserved borrower segments efficiently and at scale.

Business challenges

  • No support for seamless migration: The client’s legacy cloud lacked scalable automation and integration capabilities for large-scale data modernization, making end-to-end migration to modern infrastructure risky and operationally disruptive to business continuity.
  • High technical debt and manual validation overhead: Critical workflows like credit scoring and onboarding depended on manual checks, delaying operations and limiting traceability across key systems.
  • Disjointed product systems: Siloed legacy tools and third-party integrations (e.g., risk data feeds, verification tools) hindered governance and slowed decision-making.
  • Lack of DevSecOps and microservices frameworks: The absence of CI/CD, secure deployments, and infrastructure as code (IaC) practices slowed innovation and delayed product rollouts, such as fraud detection updates.
  • Platform limitations affecting AI/ML enablement: The client’s inflexible architecture could not support modern data science pipelines, which delayed AI-led credit models, impacting data accuracy, decision speed, and client responsiveness.

LTIMindtree solution

LTIMindtree led a zero-disruption transformation by re-architecting the client’s legacy systems into a modern, scalable, cloud-first platform on Google Cloud. The engagement was structured in two phases: initial platforming with foundational automation and complete modernization to enable AI readiness and future scalability.

Business benefits

 
95% defect removal efficiency

95% defect removal efficiency

Automated regression testing and validation utilities reduced production defects such as broken API calls, mismatched credit scores, and onboarding delays, enhancing stability across release cycles.

100% productivity gains post-migration

100% productivity gains post-migration

Zero downtime during cutover enabled credit scoring, data engineering, and client operations teams to double their throughput on the replatformed, agile-ready infrastructure.

15% reduction in tech and operational costs

15% reduction in tech and operational costs

The modernization lowered application runtime costs (compute, storage, licensing) and infrastructure overhead (support resources, manual intervention), contributing to sustained IT savings.

4% reduction in mean time to resolution (MTTR)

4% reduction in mean time to resolution (MTTR)

Enhanced visibility and traceability shortened resolution times for P1 incidents like delayed credit updates, failed loan eligibility checks, and data sync failures.

Streamlined onboarding for high-risk lenders

Streamlined onboarding for high-risk lenders

Unified systems accelerate onboarding for subprime providers such as auto lenders, rent-to-own, and credit card issuers, avoiding long integration delays, manual reconciliations, and potential client churn.

800ms to less than 700ms SLA improvement

800ms to less than 700ms SLA improvement

Performance optimization reduced average system response time, directly boosting customer satisfaction and SLA adherence.

AI/ML-ready data foundation
