Scalability and Security Hurdles

The client needed an enterprise transaction system capable of reconciling 5,000 transactions per second under strict PCI-DSS guidelines. Legacy SQL queues were locking tables, causing transaction delays and data discrepancies.

High-Throughput C# Microservices

We designed a distributed ledger using C# and .NET Core. By queuing transaction requests inside Redis streams and processing them asynchronously with stateless workers, we eliminated table locks.

• Stateless .NET Core transaction parser workers
• Encrypted TLS 1.3 transaction pipelines
• Automated daily ledger balance checks
• Redis caching layer to manage transaction rate limits
