The Challenge
A rapidly growing fintech startup was hitting the limits of their single Postgres database and monolithic API. During peak transaction times, latency would spike to over 2 seconds, causing failed payments.
Our Solution
We re-architected their critical payment path using AWS Lambda and DynamoDB.
- Decoupling: We broke the monolith into microservices.
- Event-Driven: detailed logs were pushed to Kinesis for async processing.
- Security: We implemented strict IAM roles to ensure PCI-DSS compliance.
Results
- 99.99% Uptime achieved during Black Friday.
- Latency reduced to under 100ms.
- Compliance audit passed with zero findings.
