WHAT WE BUILD FOR FINTECH COMPANIES

Financial software you own and can see all the way through, instead of a black box you rent.

Payment processing you own

Checkout, payouts, and SEPA processing built into your own software, with full visibility of every transaction and no lock-in to one provider's rails.

KYC and onboarding flows

Identity checks, document upload, risk scoring, and approval steps as configurable software, with an audit trail on every decision.

Transaction ledger and reconciliation

A tight ledger that reconciles automatically against your bank and accounting integrations, so the numbers always agree without manual investigation.

Encryption, audit trails, and data residency

Sensitive data encrypted at rest and in transit on server cores we manage, with access logging and role-based permissions. You choose the region the data lives in.

CLEAR ANSWERS

What security standards does LUX-LEET enforce for fintech software?

Financial software demands top-tier security. We engineer with mandatory 2FA, zero-knowledge encryption, comprehensive audit logging, and host on dedicated physical server cores protected by active WAF threat defense.

Do you just integrate with a payment provider, or handle payments directly?

We handle it directly. As a payment partner, we set up checkout, payouts, and SEPA processing for you in-house, plus accounting sync - no separate provider relationship for you to manage.

How does your software handle high transaction spikes?

Engineered on our lightweight PHP framework, our applications handle thousands of concurrent requests with ultra-low latency and zero template overhead.

How do you handle KYC and customer onboarding?

We build the onboarding journey - identity checks, document upload, risk scoring, and approval steps - as configurable software, with a full audit trail on every decision for your compliance team.

Can you migrate us off a third-party payment platform?

Yes. We move your checkout, ledger, and payout logic into software you own, map every historical transaction across, and run both systems in parallel until the new one is verified.

How long does a fintech build take?

It depends on scope and you get a fixed timeline in your quote. A focused dashboard or onboarding flow is weeks; a full payments and ledger platform is a larger build planned in clear sprints.
