Industries — Fintech

Fintech engineering that stands up to auditors

In fintech, the cost of a defect isn't a bug ticket — it's a reconciliation break, an audit finding, or a regulator's letter. We build and run systems where evidence, access control, and correctness are part of the delivery process, not a scramble the week before the audit.

The stakes

Where fintech projects go wrong

01

Audit season turns your engineers into evidence collectors

SOC 2 and ISO 27001 audits stall roadmaps when change logs, access reviews, and deployment records live in screenshots and memory. We wire evidence into the pipeline — every change traceable to a ticket, a reviewer, and a deploy — so the auditor gets exports, not interviews.

02

Every ledger discrepancy is a customer-trust incident

Money movement demands idempotent operations, double-entry discipline, and reconciliation that runs continuously — not a spreadsheet on the last day of the month. We design for the retry, the duplicate webhook, and the partial failure, because at transaction volume they are daily events, not edge cases.

03

Infrastructure spend grows faster than transaction volume

Compliance pressure pushes fintech teams to over-provision: everything replicated, everything retained, nothing ever deleted. Cost discipline and audit-readiness aren't opposites — right-sized environments with documented controls pass reviews and cut the bill at the same time.

FAQ

Buying software services in fintech

The questions fintech buyers actually ask us — answered the way we’d answer them on a call.

Yes — we are used to being the vendor under review. Expect signed NDAs and DPAs, named engineers with verified identities, device and access policies in writing, and prompt answers to your security questionnaire. If your review requires a control we don't have, we'll say so before you spend time on us.

Regulated environments are the assumption, not the exception: we set up fintech engagements to hold in SOC 2 Type II environments and under FCA and EU supervision. More useful than the acronyms: we design delivery so the controls auditors check — change management, least-privilege access, logging — are produced by the normal workflow, not bolted on afterwards.

The default is that we don't touch it. Development and staging run on synthetic or masked data; where production access is unavoidable, it is scoped to named individuals, time-boxed, logged, and granted through your access-management process. You can revoke everything with one action at any time.

That's the job. We ship through your CAB or approval workflow, keep deployment records in your systems, and write change descriptions your compliance team can actually read. If the process itself has become the bottleneck, our IT consulting practice can help streamline it without weakening the control.

Offboarding is a checklist, not a hope. All access runs through your identity provider so revocation is immediate, we hold no credentials in personal vaults, and we close with a written confirmation of what was accessed and what has been surrendered. Code and documentation live in your accounts throughout, so there is nothing to hand back.
