Frequently Asked Questions About FinTech Engineering

What FinTech platforms does Eastgate build? +

We build payment processing systems, cross-border remittance platforms, ESG scoring and reporting tools, digital banking and lending platforms, billing/subscription management, and regulatory compliance automation. We integrate with Stripe, Adyen, SWIFT, open banking APIs, and core banking systems.

How does Eastgate handle PCI-DSS and financial compliance? +

We architect payment flows to minimize PCI scope - tokenization, hosted payment fields, and certified gateway integrations. Our engineers build systems with full audit trails, RBAC, encryption at rest and in transit, and automated compliance checks for PSD2, MiCA, Basel III, SOX, and jurisdiction-specific regulations.

Can you integrate with our existing core banking or payment systems? +

Yes. Most of our FinTech work is integration, not greenfield. We connect new platforms with core banking systems, payment gateways (Stripe, Adyen, SWIFT), open banking APIs (PSD2), and legacy financial infrastructure via REST APIs, message queues, and event-driven architectures.

What AI capabilities does Eastgate build for FinTech? +

ML-driven fraud detection, credit scoring models, AML transaction monitoring, ESG scoring with NLP-based data extraction, automated document processing for KYC/onboarding, and predictive analytics for risk assessment. All deployed with monitoring, explainability, and regulatory audit trails.

How fast can you ramp up a FinTech engineering team? +

4-6 weeks for a full embedded team. For urgent needs, we can start with a 2-person pod in 2 weeks and scale up. Our engineers have experience with financial regulations (PCI-DSS, PSD2, AML/KYC), payment protocols (ISO 20022, SWIFT), and security-first architecture patterns.

Do you build for regulatory reporting requirements? +

Yes. We build automated reporting pipelines for SFDR, CSRD, TCFD, EU Taxonomy, SOX, and Basel III. Our ESG Scoring Platform for Seneca ESG automates data collection from 50+ sources with ML-enhanced scoring - a model we apply across regulatory reporting domains.

What makes Eastgate different from other FinTech development firms? +

ISO 27001 certified, SOC 2 aligned, 93% client retention. We're not a SaaS vendor - we build custom financial platforms. 200+ engineers with real experience in payment processing, regulatory compliance, and security-first architecture. AI-augmented delivery built into every engagement.
