// About the Project
Project Overview
The client is an up-and-coming Fintech player focused on simplifying online payments for eCommerce. They decided to build a digital gateway platform handling different payment methods — from credit cards to digital wallets — while meeting PCI DSS standards.
As a new company entering the Fintech market, the client needed to build a truly reliable platform on par with competitors. The system needed to handle thousands of transactions at once and stay responsive during peak times like Black Friday.
UppLabs took on end-to-end project management and product ownership, designing microservices architecture so each payment method works independently, with ML-based fraud detection that catches fraud in milliseconds.

// Challenges
Problems We Solved
High Volume Transactions
Needed scalable, efficient architecture that could stay responsive during peak times like Black Friday with thousands of simultaneous transactions.
Fraud Detection
Required a strong fraud detection mechanism that could identify suspicious transactions in real-time without interrupting the payment experience.
PCI DSS Compliance
Non-negotiable compliance requirement since it directly impacts the ability to handle credit card transactions legally and securely.
Lack of In-House Management
The client needed a partner who could handle both technical and process ownership, letting the core team focus on business.
// Solutions
How We Delivered
Microservices Architecture
Each payment method works independently. Docker for containerization and K8s for orchestration made the system future-proofed for growth.
ML-Based Fraud Detection
ML system that learns from transaction patterns and identifies anomalies. Using Redis for quick data access, catching fraud in milliseconds.
PCI DSS Certification
AES-256 encryption, OAuth2 for secure logins, JWT tokens for sessions. Passed PCI-DSS certification on the first try.
eCommerce Integrations
Developed APIs, SDKs, and plugins for Shopify, WooCommerce, and Adobe Commerce — users can integrate in minutes.
