The Challenge

High cart abandonment rates during gaming flash sales occurred because traditional payment processors failed to scale under high-concurrency requests. We engineered an ultra-low latency gateway leveraging our custom software development expertise.

The Blueprint

We built a concurrent Go gateway using a Redis-backed queue and distributed locking, capable of dynamic multi-acquirer transaction routing and smart retries.

The Execution

Implemented custom lightweight API SDKs for seamless client-side checkouts, scaling infrastructure with auto-healing load balancers on AWS ECS.
