SecureTransact API
Enterprise-Grade Secure Transaction Processing Platform
A high-security transaction processing platform built on .NET 9 with enterprise-grade encryption, real-time event processing, and zero-trust architecture. Designed for financial institutions demanding the highest levels of data protection and regulatory compliance.
The Challenge
Financial institutions needed a transaction processing API capable of handling high throughput while maintaining military-grade encryption, zero-trust access controls, and full regulatory compliance across multiple authentication standards.
Our Solution
We engineered a .NET 9 Minimal API platform with CQRS via MediatR, AES-256-GCM encryption at rest, Argon2id password hashing, and JWT RS256 token authentication. Azure Service Bus and RabbitMQ handle async event processing, while Entity Framework Core 9 with PostgreSQL 17 provides robust data persistence. Infrastructure is fully codified with Terraform and Azure Bicep, deployed on Azure Container Apps with Kubernetes orchestration.
The Results
The platform achieves sub-50ms average latency with 99.99% uptime SLA. Full OpenTelemetry observability pipeline feeds into Seq and Grafana for real-time monitoring. Automated security scanning via CodeQL and SonarQube ensures continuous compliance, while Testcontainers enable comprehensive integration testing across all services.
