12 modules. 12 chapters per module. 144 chapters total.
12 modules, each with 12 chapters (144 chapters total), text-based, plus downloadable templates and a hand-built implementation playbook delivered alongside course access.

The situation this course is for

Who this is for

Full Stack Developer working in a regulated payments environment who owns cross-layer design and debugging

Who this is not for

Frontend-only developers, backend-only engineers, or product managers without hands-on implementation responsibility

What you walk away with

  • Confidence in tracing transaction flow across UI, API gateway, and settlement layers
  • Clear mental model for isolating latency or failure in distributed payment workflows
  • Ability to justify architecture choices using established patterns (e.g., idempotency, circuit breaking, tokenization boundaries)
  • Precision in documenting service interactions for audit or peer review
  • Fluency in the standards shaping modern payment platform design (PCI-DSS, ISO 20022, OAuth2 for payments)
