Fintech · Software development
Fintech software, built by people who've done it before.
Banking apps, payment flows, lending platforms and back-office systems with the security and auditability finance demands. We design for reconciliation, idempotency and audit from day one, because in finance a duplicated transaction is not an edge case, it is a complaint.
The realities of fintech software.
- Money movement needs idempotent APIs, double-entry ledgers and reconciliation, not just a payments SDK
- KYC, AML and PCI DSS requirements shape architecture, not just a checklist at the end
- Regulators and auditors expect complete, immutable audit trails
- Downtime and latency directly cost revenue and trust
Solutions we've delivered in this sector.
- Digital banking and wallets
- Payment gateway and KYC integrations
- Lending and credit scoring platforms
- Reporting, reconciliation and audit tooling
- Fraud detection and risk scoring
Compliance we design for: PCI DSS, SOC 2 readiness, GDPR
What we have built in fintech
Fintech projects have included a digital wallet with a double-entry ledger, KYC onboarding and card-payment integration, built over six months by four engineers, a QA engineer and a project manager. Another engagement delivered a lending platform with application workflow, credit-scoring integration and repayment scheduling in four months with three engineers. We have also built reconciliation and reporting tooling that matches payment-provider settlements to internal records daily, a two-engineer, ten-week project that replaced a manual month-end process.
Compliance and integration checklist
- PCI DSS scope minimised by tokenising card data through Stripe, Adyen or a local acquirer
- Idempotent payment APIs and a double-entry ledger so no transaction can be applied twice
- KYC and AML provider integration (identity verification, sanctions screening) with audit trails
- Immutable audit logs and change history for every financial record
- SOC 2 control evidence: access reviews, change management, logging and incident response
- GDPR DPA and data residency for European customers
- Reconciliation jobs with alerting on every mismatch

Fintech questions, answered.
Have you built payment systems before?
Yes, including wallet ledgers, card-payment integrations and reconciliation tooling. We keep card data out of your systems wherever possible by using tokenized providers.
Can you help with SOC 2?
We build the controls SOC 2 expects, such as access reviews, change management and logging, and hand auditors the evidence they ask for.
Do you work with regulated clients in the EU?
Yes. GDPR data mapping and a DPA are part of every EU fintech engagement.
