FinTech & Engineering

Deep FinTech expertise. Broad engineering capability.

Payments and financial systems are a deep specialisation. Engineering capability extends well beyond them.

Payments and financial systems demand a kind of correctness most software does not. A retry that posts twice, a settlement that replays after an outage, a ledger that disagrees with the processor — these are not edge cases, they are the work.

Alongside that specialisation we do general software engineering: services, APIs, integration, modernisation and data architecture, across whichever stack a system already uses.

Where transaction systems fail

  • A retry posts the payment twice.
  • Reconciliation runs for hours and still does not balance.
  • The ledger and the processor disagree and neither is obviously wrong.
  • A replay after an outage double-settles.
  • One slow consumer blocks the partition and the queue stalls behind it.
  • A saga step has no compensating action, so failure leaves money in limbo.
  • Throughput is comfortable until month-end.

Beyond FinTech

The same primitives — idempotency, exactly-once delivery, compensating actions, reconciliation — apply anywhere an action must happen once and only once. That includes automated systems acting on a business’s behalf.
