FinTech & Banking Software Engineering for High-Security Financial Systems
Build PCI-DSS compliant payment gateways, Plaid open banking integrations, real-time transaction ledgers, and AI fraud detection systems.
Engineering Mission-Critical Software for Banks & FinTech Startups
Financial technology requires sub-second processing speeds, zero transaction data loss, and strict regulatory compliance. Our FinTech software engineering team builds custom neo-banking portals, payment gateways, and wealth management platforms.
We ensure your financial software meets PCI-DSS and SOC2 security standards, incorporates automated KYC/AML verification, and scales reliably on AWS cloud infrastructure.
FinTech Tech Stack
FinTech Deliverables
PCI-DSS Compliant Payment Gateways
High-throughput Stripe, Plaid, and custom payment processor integrations built for zero transaction loss.
Real-Time Fraud Detection & Risk AI
Machine-learning anomaly detection algorithms that flag suspicious transactions and unauthorized access in real time.
High-Frequency Ledger & Banking APIs
Sub-50ms transaction processing ledgers built with PostgreSQL, Redis, and multi-region AWS cloud isolation.
KYC / AML Automated Verification
Automated Know Your Customer (KYC) and Anti-Money Laundering (AML) identity verification workflows with instant ID validation.
PCI-DSS Compliance, Open Banking & AI Fraud Risk Engines
PCI-DSS Level 1 Security Architecture & Stripe Tokenization
Financial software applications demand bank-grade security protocols and zero transaction processing latency. We build custom payment gateways and ledger systems engineered for PCI-DSS compliance standards.
By tokenizing cardholder data and securing sensitive financial keys in isolated hardware security modules (HSMs), we protect your banking platform against data breaches while ensuring 99.999% transaction reliability.
Plaid Open Banking API Integrations & Real-Time Ledgers
Modern FinTech platforms rely on seamless open banking connectivity. We integrate Plaid, Yodlee, and custom banking APIs to enable real-time account verification, instant ACH transfers, and transaction categorization.
Our high-performance transaction ledgers use PostgreSQL ACID compliance and Redis caching layers to process thousands of transactions per second (TPS) with sub-50ms query response times.
AI Machine-Learning Fraud Detection & Automated KYC/AML
Protect your financial platform against fraudulent transactions and identity theft. We build real-time Python machine-learning risk scoring models that analyze transaction parameters instantly.
Integrated with automated KYC/AML verification APIs (Jumio, Onfido), our solutions streamline user onboarding while flagging high-risk activities before fraudulent payouts occur.
