FinTech & payments software development

Financial software,
secure from day one.

We build payment platforms, financial products and integrations where correctness, uptime and compliance are requirements from the first commit — not a checklist before the audit.

In FinTech, the hard parts are invisible in a demo: idempotent payment flows, reconciliation that always balances, audit trails, fraud signals, and infrastructure that passes a PCI-DSS assessment. Getting them wrong costs money and trust.

Our senior engineers have rebuilt a legacy payment system processing 50K+ transactions a day with real-time fraud detection and multi-currency support across 40+ countries, and delivered a PCI-DSS Level 1 certified payment acceptance platform covering in-store POS and online checkout for a retail network.

FAQ

Frequently asked questions

Have you built PCI-DSS compliant systems?

Yes. We delivered a payment acceptance platform certified at PCI-DSS Level 1 and a payment processing platform on PCI-DSS Level 1 compliant AWS infrastructure. Compliance is handled at both the infrastructure and application layer.

Can you modernise our legacy payment system?

Yes. We have rebuilt legacy payment systems while keeping the business running — migrating in stages, running old and new paths in parallel, and reconciling until the new system is proven.

Which payment providers do you integrate?

We integrate the providers you already use or help you choose — Stripe, local acquirers and bank APIs — behind an abstraction so adding or switching providers does not mean a rewrite.

How do you approach security?

Least-privilege access, encryption in transit and at rest, audit trails for every money movement, and threat modelling for new flows. Senior engineers review every change that touches payments.

Do you work with startups or established companies?

Both. We help FinTech startups ship a compliant MVP and work as a nearshore team for established companies scaling their payment infrastructure.
