Frequently Asked Questions
How do you ensure compliance with financial regulations like PSD2 and SOC 2?+
We architect fintech products with compliance baked in from day one — scoped permission models, audit logging, encrypted data pipelines, and infrastructure patterns that satisfy SOC 2 Type II, PSD2, and GDPR requirements. We work alongside your legal and compliance teams to document every decision.
Can you integrate with payment processors like Stripe, Plaid, or Adyen?+
Yes. We have deep experience integrating with Stripe (payments, Connect, Billing), Plaid (bank account linking, identity), Adyen, and other major payment infrastructure providers. We handle webhook reliability, idempotency, and reconciliation edge cases.
How do you handle real-time data in financial dashboards?+
We use a combination of WebSockets, server-sent events, and optimistic UI patterns to deliver sub-second data updates without sacrificing accuracy. Our architecture ensures consistency between real-time feeds and the source of truth in your database.
What security standards do you implement for fintech applications?+
We follow OWASP security guidelines, implement CSP headers, rate limiting, MFA flows, and session management best practices. All sensitive data is encrypted at rest and in transit, with no secrets stored client-side.
Why choose Nextcraft over a generalist agency for fintech?+
Fintech products fail when engineers treat them like regular web apps. We understand the stakes — a payment bug or a data breach isn't a hot-fix situation. Our team has shipped production fintech products and knows where the sharp edges are.
Do you offer post-launch support?+
Yes. We provide long-term partnership options to iterate on features, optimize performance, and scale your infrastructure as your user base grows.
