Financial services & payments

Payments punishes vagueness faster than any other sector. A card authorisation has to finish inside a fixed window, and everything you want to happen inside it — risk scoring, fraud checks, currency conversion — has to fit. Go over and the bank times out and the sale is gone. Get the record-keeping wrong and somebody spends a month reconciling by hand. We work on the parts that cannot simply be tried again: making sure a retry cannot take a payment twice, that two systems always agree on what was charged, and that every movement of money can be replayed and explained afterwards. Where the existing system is a decade-old monolith, we take the busiest path out of it first and leave the rest alone, rather than proposing a rewrite nobody can fund. Compliance shapes the build from the first week instead of arriving as a document at the end: reducing how much of your estate falls inside PCI scope, meeting the strong customer authentication rules, and keeping records good enough that a regulator asking about one transaction from eighteen months ago gets an answer the same day. Typical engagements: speeding up the authorisation path, fixing ledger and reconciliation problems, moving off an overnight settlement window, and building one stream of events that the fraud and reporting teams can both read from.
