The challenge
The startup needed to connect to multiple payment processors and banks but had no infrastructure to handle webhooks, retries, or reconciliation. Their MVP was blocked on backend plumbing, not product ideas.
Our approach
We designed a cloud-native payment orchestration layer on AWS with webhook ingestion, idempotent transaction handling, automated reconciliation jobs, and a clean REST API their frontend team could call without touching payment provider SDKs.
