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
Payments and billing we have shipped
Our fintech work to date sits inside larger products: Stripe subscriptions and Stripe Connect payouts to agency partners in TamTracker, card payments, guide payouts and Apple and Google subscriptions in LogFish, usage-based billing in Edge OCR and a credit-based vendor economy in Seek My Service. Paint Nite runs idempotent Stripe payments in a national ticketing checkout. For wallets, lending and banking products we add the patterns finance demands: a ledger as the source of truth, idempotent payment handling, reconciliation against provider reports and audit trails. For the app-specific detail see fintech app development, payment gateway integration and PCI DSS compliant development.
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: card payments, subscriptions, Stripe Connect payouts and usage-based billing inside larger products, including idempotent Stripe payments in the Paint Nite ticketing checkout. 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.
