A major North American bank-backed payment solution set out to redesign online checkout – without launching another wallet app. The goal: remove friction at the point of payment while keeping security at bank-grade standards.

Key challenge and overview

The digital payments market is crowded. Big-tech wallets dominate consumer mindshare. Merchants demand low fraud, high approval rates, and minimal checkout drop-off. Banks require strict compliance, resilience, and control.

This payment platform chose a distinct model: no separate app, no manual card entry, no user registration. Instead, it relied on direct bank integrations and tokenization to power checkout inside the banking ecosystem itself.

That strategy required a strong engineering base. Core product domains had to scale fast, integrate with multiple institutions, and remain stable under transaction load. Time-to-market mattered—but so did reliability.

Our approach

CBTW embedded cross-functional pods within the client’s product organization, taking ownership across engineering and operations.

We focused on creating structure and repeatability in a complex environment:

  • Defined domain-driven service boundaries to reduce system coupling and clarify ownership
  • Implemented automated testing standards integrated into daily development cycles
  • Built CI/CD pipelines to support frequent, controlled releases
  • Introduced SRE practices for monitoring, incident management, and uptime stability
  • Standardized workflows across frontend, backend, and QA to enable parallel scaling

The teams worked across React frontend, Java/Spring Boot backend services, QA automation (SDET), and site reliability engineering to support production from day one.

Benefits

The result was a platform capable of scaling with confidence:

  • Shorter release cycles with lower regression risk
  • Improved production stability through structured SRE oversight
  • Faster onboarding of new integrations thanks to clear domain ownership
  • A technical base aligned with banking-grade security expectations

Most importantly, the platform could deliver a checkout experience that reduces friction and fraud—two of the biggest drivers of cart abandonment in e-commerce.

Conclusion
