-
How do you ensure PCI-DSS Level 1 compliance when building payment software?
We enforce compliance by isolating sensitive Primary Account Numbers (PANs) from your application servers using hosted payment fields, iFrames, and direct client-side tokenization. Tokenized data routes directly to certified processors, significantly reducing your audit scope and eliminating card data breach exposure.
-
Can custom financial software integrate with legacy core banking platforms?
Yes. We build custom API middleware that interfaces with core banking engines like Fiserv, FIS, and Jack Henry. Our connectors translate modern REST or GraphQL requests into proprietary legacy protocols, enabling real-time balance inquiries, account creation, and transaction posting without replacing legacy cores.
-
How do you maintain transactional integrity in high-volume ledger applications?
We design double-entry ledgers enforcing strict ACID database properties where every debit is balanced by an equal credit. Using optimistic locking, distributed event logs (Apache Kafka), and event-sourcing patterns, we prevent race conditions and balance drift under high concurrent transaction loads.
-
What standards do you use to support Open Banking and ISO 20022 exchange?
We implement Open Banking architectures compliant with FDX, UK Open Banking, and ISO 20022 financial messaging formats. Our APIs enforce OAuth2 framework security with Mutual TLS (mTLS) and fine-grained consent management for secure data sharing with third-party aggregators and payment networks.
-
Who owns the intellectual property and source code developed for our institution?
Your financial institution retains 100% ownership of all custom source code, database schemas, and integration scripts. We transfer all repositories and deployment documentation upon completion with zero recurring licensing fees, per-transaction charges, or vendor lock-in.
-
How do you protect financial data during database migrations and cloud modernizations?
We construct encrypted ETL pipelines using AES-256 encryption in transit and at rest. Before live cutover, we conduct dry runs and checksum validation in staging environments, followed by zero-downtime cutover techniques like dual-writing or change-data-capture (CDC) replication.
-
How do custom KYC/AML pipelines reduce onboarding drop-off while maintaining compliance?
Automated pipelines replace manual review by integrating identity verification APIs (such as Persona or Alloy) to perform OCR scans, liveness checks, and sanction screenings in seconds. Low-risk applicants are approved instantly to fund accounts, while only flagged applications route to compliance staff.
