Large-scale financial trading platform
Enterprise system for secure, scalable and auditable financial transaction processing, built for high performance and 24/7 availability.
Context
Financial organization with very high daily transaction volumes, strict compliance, auditability and 24/7 availability requirements. The existing platform no longer supported business growth and had become a major operational risk during peak periods.
Challenge
• High latency in transaction processing during peak periods • Limited scalability during peak load conditions • Increased operational risk and blockages in critical business flows • Reduced visibility into system state, incidents and failures
Solution
We designed and implemented a distributed, event-driven architecture with asynchronous processing and robust retry, idempotency and failover mechanisms. The solution was built with emphasis on: • clear separation of responsibilities (bounded contexts) • data consistency and integrity • complete transaction traceability • real-time monitoring and alerting
Technologies
TypeScript, React, Node.js, PostgreSQL, AWS (cloud infrastructure, auto-scaling, observability)
Impact
• stable processing of very high transaction volumes without performance degradation • significant latency reduction in critical flows • elimination of operational blockages and recurring production incidents • high availability including during peak periods • increased confidence of business and operations teams in the system
Our Role
Software architecture, system design, full-stack development and technical leadership
