Card scope creep
PCI DSS audit scope quietly grows with every new microservice. We tokenize early and isolate cardholder data to keep the audit boundary small.
GDPR PCI DSS AI-native
Fintech Software Development Services for Regulated US and EU Operators
YuSMP Group builds production fintech software for payments, lending, wallets, neobanks and capital-markets desks across the US and EU. Eighty senior engineers ship inside PCI DSS scope, partner with QSAs on assessments, and deliver KYC/AML, open banking and real-time payment flows that satisfy regulator-grade scrutiny. xRouten payment routing improved auth rates by 4.1 points and cut latency 38%.
We deliver custom fintech engineering for four buyer profiles: payment processors and PSPs moving card, ACH, SEPA and FedNow volume; consumer and SMB lenders running KYC/AML, underwriting and servicing; wallet, BNPL and neobank teams building on banking-as-a-service rails; and capital-markets desks integrating market data, execution and post-trade workflows. Our delivery teams operate inside PCI DSS scope, coordinate assessments with partner QSAs, and design to PSD2, open banking, FedNow, SEPA and US state money-transmitter expectations. GDPR alignment, SOC 2 Type II progress and ISO 27001 readiness sit underneath every engagement.
Challenges
Industry challenges we solve
PSD2 SCA friction
Strong customer authentication kills conversion when applied bluntly. We tune risk-based exemptions and 3DS2 flows for measurable uplift.
Legacy core integration
Mainframe and aging core banking systems block product velocity. We wrap them with event-driven facades and progressive strangler patterns.
AML signal noise
Rule-only monitoring drowns analysts in false positives. We add ML scoring and feedback loops to lift true-positive rate without breaking auditability.
DORA readiness
ICT risk register, third-party concentration and resilience testing are now non-negotiable. We engineer them in, not bolt them on.
Cross-border data
Multi-jurisdiction deployments need careful data residency and SCC handling. EU data residency by default, US options on request, with clear lawful basis.
