Production-grade Web & Blockchain engineering — no templates, no shortcuts.
Most dev shops can write payment code. Few understand the regulatory architecture, security requirements, and trust signals that make a fintech product actually work in production — and keep working as you scale.
What this means
Financial products operate under regulatory obligations that most software teams don't account for at the architecture level. PCI-DSS compliance, KYC/AML workflows, data residency rules, fraud prevention, and audit trail requirements are structural — not features you add later.
A fintech platform that looks production-ready but isn't architected for security and compliance will fail at the moment it scales — or the moment a regulator asks questions. Either outcome is expensive.
Nextelligentia engineers fintech systems from the compliance layer up. Every data flow, every API integration, every user-facing transaction is designed with security and auditability in mind from day one.

Services
Strategy, security, development, and compliance in one team. No subcontractors. No hand-offs. End-to-end, always.
We scope every system around your regulatory environment — PCI-DSS, KYC/AML, GDPR — before a single line of code is written. No retrofitting compliance later.
Included on all projects
Plaid, Stripe, open banking APIs, core banking connectors — integrated cleanly and securely so your platform talks to the financial infrastructure it needs to.
Included on all projects
Custom payment flows, multi-currency support, escrow logic, and wallet infrastructure built with fraud prevention and auditability baked in from the start.
Included on all projects
End-to-end identity verification flows with third-party KYC providers, document checks, and automated AML screening — built for scale, not just box-ticking.
Included on all projects
Financial operations dashboards with real-time transaction feeds, anomaly detection hooks, and audit-ready data exports your compliance team will actually thank you for.
Included on all projects
End-to-end encryption, role-based access control, rate limiting, and architecture designed to pass third-party pen tests — not hope they don't run one.

Book intro callHow it works
Every phase has a defined output and your sign-off before we proceed. In fintech, a decision made wrong at architecture costs far more to fix at launch.
Everything in-house. Architecture, compliance scoping, security design, development, and QA — all delivered by the Nextelligentia team. No subcontractors. One consistent team from kickoff to go-live.
Before any architecture decisions, we map your regulatory obligations — PCI-DSS, KYC/AML, GDPR, FCA requirements — so compliance is built in, not bolted on.
You get a detailed technical plan covering data flows, encryption strategy, third-party integrations, and a fixed price in writing. No surprises.
Fintech users are skeptical by default. We design trust-first interfaces — clean onboarding, clear transaction states, and dashboards that reduce support volume.
Payment APIs, banking integrations, KYC providers, and fraud detection hooks — wired up correctly with regular check-ins so you always know where things stand.
Pre-launch security hardening, penetration-readiness review, cross-device QA, and a monitored deployment. We don't push to production until it's ready.
Ongoing fintech retainer
Regulation changes. APIs get updated. New features need to ship fast and securely. Our ongoing retainer keeps a senior engineering team plugged into your fintech product — monitoring, improving, and building as you grow.
Fit check
Financial product engineering is high-stakes. We'd rather be upfront about fit than take on a project we can't deliver properly.
