Overview

A commerce and platform build for a financial technology business, spanning the customer-facing storefront and the administration behind it.

01 — The challenge

What made it hard.

Ledgers must balance to the cent across providers, currencies and retries. Approximate is the same as wrong.

01

Onboarding compliance

KYC and AML checks have to satisfy regulation without becoming the reason users abandon signup.

02

Provider dependency

Payment rails fail in ways you do not control. The system has to degrade without losing money.

03

Audit expectations

Regulators ask what happened on a specific date to a specific account. The answer has to take minutes.

02 — The product

What we shipped.

A commerce and platform build for a financial technology business, spanning the customer-facing storefront and the administration behind it.

03 — The build

How it holds up.

Double-entry from the first commit, idempotency on every money-moving endpoint, and a reconciliation job that runs whether or not anyone is watching.

The system

Transactional paths are idempotent and separately monitored from the content layer, so a marketing change cannot affect money movement.

04 — Ownership

Theirs, from day one.

Repositories, cloud accounts and documentation sat with the client throughout. Senior engineers wrote the production code rather than specifying it.
