Fintech & Payments

Payments software that holds up under scrutiny.

We build and audit the platforms behind payments, lending and financial operations — secure, compliant, and reliable when real money is moving.

Fintech doesn't forgive shortcuts. A dropped transaction, a failed reconciliation or a gap in your audit trail isn't a bug — it's a liability. We engineer for that reality: EU-based, GDPR-native, and built to survive an auditor, a regulator and a traffic spike on the same day.

What fintech teams bring to us

Compliance can't be bolted on

GDPR, PSD2 and PCI-DSS shape the architecture from day one — consent, EU data residency, encryption and audit trails, not a checklist bolted on at the end.

Reliability when money moves

Idempotent payment flows, exactly-once processing, reconciliation you can trust, and no silently lost transactions under load.

Security under real threat

Encrypted data, least-privilege access, careful secrets handling and incident readiness — reviewed the way an attacker would.

Legacy that can't keep up

Modernize aging cores and integrations without downtime, using staged, reversible migrations rather than risky big-bang rewrites.

Fintech questions

Can you work within our compliance requirements?

Yes. We build to GDPR by default and design around PSD2 and PCI-DSS obligations — EU data residency, encryption, access control and audit trails are part of the architecture, not an add-on.

Can you audit our existing payment platform?

Yes. Our Advisory & Audits engagement reviews architecture, reliability, security and compliance, and ends with a written report and a prioritized remediation plan. If you want, our engineers then execute the fixes.

Do you handle high-volume processing and reconciliation?

Yes. We design idempotent, exactly-once flows and reconciliation pipelines built to stay correct under load, with the observability to prove it.

Where is our data hosted?

In the EU by default. We're a Warsaw-based studio and treat EU data residency and GDPR as the starting point, not an option.
