Core Challenges We See.

Regulatory Compliance Complexity

Financial services face overlapping regulations varying by geography: PCI-DSS for payments, KYC/AML for onboarding, SOX for public companies, state licenses, GDPR for European customers. We build compliance rules as configuration, maintain regulatory libraries, implement audit trails, automate reporting.

Transaction Processing at Scale

Financial transactions require absolute correctness at high volume. Lost transactions, duplicate charges, rounding errors create regulatory risk. We architect for strong consistency, implement idempotency preventing duplicates, use distributed transactions, maintain comprehensive audit logs. Process millions reliably.

Fraud Without Friction

Fraud costs mount while false positives anger customers. Rule-based systems generate excessive alerts, ML models lack explainability. We implement risk scoring combining rules and ML, route high-risk to human review, learn from outcomes, maintain false positive rates under 2%.

Payment Gateway Complexity

Integrating multiple payment processors requires handling different APIs, error codes, settlement timelines, retry logic. Single interface complexity multiplies across providers. We abstract payment operations behind unified API, handle provider-specific quirks, manage routing and failover.

High Availability Requirements

Financial systems cannot afford downtime. Every minute offline costs revenue and reputation. We design for 99.99% uptime: multi-region deployment, automated failover, database replication, health monitoring, disaster recovery. Proven resilience under load.

Data Security at Every Layer

Financial data attracts sophisticated attacks. Single vulnerability exposes customer funds and data. We implement defense in depth: encryption everywhere, network segmentation, penetration testing, bug bounty programs, security monitoring, incident response. Security as foundation.

Solutions We Build.

Payment Processing Systems

Integrate with Stripe, Adyen, PayPal. PCI-compliant tokenization, recurring billing, multi-currency support, comprehensive error handling and retry logic.

KYC/AML Compliance

Identity verification, document validation, sanctions screening, adverse media checks, risk scoring. Integration with Jumio, Onfido, ComplyAdvantage.

Fraud Detection Engines

Real-time transaction monitoring, anomaly detection, device fingerprinting, velocity checks, ML-based risk scoring. Human review workflows for flagged items.

Trading Platforms

High-frequency trading systems, order matching engines, market data feeds, real-time risk management. Low-latency architecture with audit logging.

Banking Core Systems

Data, Security & Compliance.

PCI-DSS Compliance

Never store raw card data, use tokenization from payment processors. Encrypt all sensitive data at rest and in transit. Network segmentation isolating payment systems. Quarterly vulnerability scans and annual penetration testing. Access control with least privilege.

Transaction Security

Idempotency keys preventing duplicate transactions. Distributed locking for critical operations. Database constraints preventing duplicate records. Two-phase commit for multi-system transactions. Event sourcing enabling complete transaction history audit.

Data Protection

AES-256 encryption at rest, TLS 1.3 in transit. Key management systems for secure key storage and rotation. Tokenization for sensitive data. Data masking in non-production environments. Secure deletion procedures for data retention compliance.

Audit & Monitoring

Comprehensive logging of all financial operations. Real-time fraud monitoring and alerting. Security information and event management (SIEM). Regular security assessments and penetration testing. Incident response procedures and runbooks.

Frequently Asked Questions.

How do you ensure PCI-DSS compliance for payment systems?
Never store raw card data; use tokenization from payment processors. Encrypt all sensitive data at rest (AES-256) and in transit (TLS 1.3). Network segmentation isolating payment systems. Quarterly vulnerability scans and annual penetration testing. Access control with principle of least privilege. Comprehensive logging of all access to cardholder data. Work with QSA for formal compliance validation.
What KYC/AML solutions do you integrate with?
Jumio and Onfido for identity verification, Plaid for income/employment verification, Socure for synthetic identity detection, ComplyAdvantage and Dow Jones for sanctions/PEP screening, LexisNexis for risk scoring, IDology for knowledge-based authentication. Can integrate with less common providers or build custom verification workflows. Typical integration takes 2-3 weeks.
How do you prevent duplicate transactions?
Idempotency keys ensuring same request processed once regardless of retries. Distributed locking for critical operations. Database constraints preventing duplicate records. Two-phase commit for multi-system transactions. Event sourcing enabling complete transaction history audit. Testing simulating network failures, retries, concurrent requests.
What does fintech platform development cost?
Varies by complexity: payment integration ($30k-60k), basic lending platform ($80k-150k), trading system ($150k-300k+), full neobank ($500k-2M+). Security and compliance add 30-40% to base development. Ongoing costs include fraud monitoring, compliance updates, security assessments, infrastructure. Factor licensing and insurance costs.
How long does fintech development take?
Timeline depends on scope: payment integration (2-3 months), lending platform (4-6 months), trading system (6-9 months), neobank (12-18 months). Includes security review, compliance validation, integration testing, load testing, regulatory approval processes. Phased approach recommended: launch MVP, validate product-market fit, then expand.
How do you achieve high availability for financial systems?
Multi-region deployment with automated failover. Database replication across regions. Load balancing and health checks. Circuit breakers preventing cascade failures. Rate limiting protecting against overload. Comprehensive monitoring and alerting. Disaster recovery procedures tested quarterly. Capacity planning for 3x peak load. 99.99% uptime SLA.
