FAQ

Frequently Asked Questions

Answers to common questions about our banking software development process, timelines, and compliance capabilities.

Core banking migrations typically range from 9 to 18 months, depending on the complexity of the existing system, the number of integrations, and the volume of accounts. We use a phased strangler-fig approach to ensure continuous operations throughout, with no single cutover event that could risk downtime.

Yes. We have delivered and maintained PCI DSS Level 1 environments for payment processors and commercial banks. Our security architects are trained QSAs and work directly with your compliance team to ensure all cardholder data environments meet the full PCI DSS v4 control set.

We have certified engineering teams on both AWS (using GovCloud and FinServ landing zones) and Microsoft Azure (Azure for Financial Services). We can also work with hybrid cloud models and private cloud deployments where required by regulatory or data sovereignty requirements.

Our 24/7 Support & Ops team includes dedicated compliance engineers who monitor regulatory updates across all major jurisdictions. We proactively identify how upcoming regulation changes will affect your platform and provide impact assessments and implementation roadmaps before deadlines arrive.

Absolutely. We have extensive integration experience with Temenos T24/Transact, Finastra Fusion, Oracle FLEXCUBE, FIS, and Fiserv. We can build custom modules, integration layers, open banking wrappers, and digital channels on top of your existing core system without requiring a full replacement.

Our typical minimum engagement is a 3-month, 3-engineer dedicated team, or a fixed-price discovery & architecture phase starting at $40,000 USD. We work with financial institutions of all sizes — from Series A neobanks to top-50 commercial banks — and tailor the team size and commercial structure accordingly.
