Payments delivery ยท Case studyIn-app payments shipped end to end in approximately three months.
Blain designed and shipped a confidential healthcare client's card-present application flow across external terminals, tokenization, and financial reconciliation.
The delivery
The work joined the in-app experience to Clover terminals and covered tokenization, application behavior, and ledger reconciliation. These paths had to work together because a successful user interaction is not enough if the financial state cannot be verified afterward.
This page describes Blain's past delivery experience. It does not identify the client, claim ownership of the client's product or intellectual property, or claim a PCI certification or audit result.
What it demonstrates
- Ownership of a consequential integration from architecture through delivery.
- Experience connecting software, external hardware, payment flows, and ledgers.
- Practical handling of failure paths and compliance-aware boundaries.
The reusable pattern
Consequential automation needs bounded inputs, explicit approvals, observable outcomes, reconciliation, and recovery. AI workflows require the same engineering discipline when they affect customers, records, money, or operations.
Validate the workflow before the build.
The one-week AI Workflow Alignment Sprint tests the critical flow and produces an implementation-ready handoff.
