ITGix Ltd

The customer - a financial services division of a major German automotive enterprise - needed to modernize its AWS-based transaction processing platform to support sensitive payment and cardholder data workflows with high performance, security, and regulatory compliance.

Challenges included:

• Ensuring PCI-DSS-compliant storage for financial and sensitive transactional data.
•  Providing strong data consistency and atomic operations to guarantee financial integrity.
• Achieving scalable, predictable performance as transaction volumes increased.
• Maintaining private, secure database access with no exposure to the public internet.
• Enforcing environment isolation and granular access control across teams.
• Delivering fully automated, auditable infrastructure provisioning to support compliance and governance. 

What We Delivered:

Solutions and Achievements Architecture & Core Solution:

We designed and implemented a cloud-native, DynamoDB-centric architecture on AWS that met enterprise-grade scalability, security, and compliance requirements while minimizing operational overhead.

Key components and accomplishments included:

• Fully managed serverless data store: Amazon DynamoDB served as the backbone for configuration and high-volume transaction histories, delivering predictable performance without operational overhead as load increased.
•  ACID-compliant transactions: DynamoDB Transactions (TransactWriteItems) ensured atomic balance updates and consistent logging to maintain financial integrity.
•  Optimized data modeling: Use of high-cardinality partition keys, time-based sort keys, and Global Secondary Indexes (GSIs) aligned the model with real application access patterns.
•  Data lifecycle automation: Time to Live (TTL) policies automatically removed transient and compliance-sensitive data.
• Resilience and security: Point-in-Time Recovery (PITR) and VPC Endpoints ensured reliable backups and kept all database traffic private within AWS.
