Modernizing payment infrastructure for high-volume transactions
ScalePay is a cross-border payment platform processing millions in daily transactions. Their legacy monolithic infrastructure was experiencing bottlenecking during peak transaction windows, leading to latency spikes and transaction timeouts.
The Core Challenge & Pain Points
A leading payment processor was struggling with legacy infrastructure that couldn't scale to meet peak demand, resulting in failed transactions and customer dissatisfaction.
Key Technical Obstacles
Engineering Strategy & Solution
We architected and led the migration to a microservices-based architecture. Implemented event-driven patterns with Kafka for real-time processing and improved reliability.
Architecture & Implementation Highlights
Event-Driven Microservices: Decoupled ingest, reconciliation and settlement pipelines using Apache Kafka.
Multi-Region Kubernetes Deployment: Automated failover and horizontal pod autoscaling based on throughput metrics.
Idempotent Payment Engine: Redis cluster with distributed lock manager ensuring zero duplicate charges.
Optimized PostgreSQL Database Layer: Sharded read replicas and connection pooling via PgBouncer.
