Backend Migration from Node.js to Golang
Redesigning high-concurrency services in Golang to leverage lightweight goroutines, reducing API latency by over 50% and improving stability.
The Challenge
The Node.js backend struggled with high concurrency, memory leaks, and inconsistent performance under load. Single-threaded event loop limitations caused bottlenecks, and the application was difficult to scale horizontally. The client needed a more performant, concurrent solution that could handle millions of requests reliably.
Our Solution
We migrated the backend to Golang with high-concurrency architecture
Goroutine Concurrency
Leveraged Go's lightweight goroutines for handling thousands of concurrent requests with minimal memory overhead.
gRPC Implementation
Implemented gRPC for high-performance inter-service communication with protobuf serialization and streaming.
Microservices Architecture
Redesigned monolithic services into microservices with proper separation of concerns and independent scaling.
Performance Optimization
Optimized database connections, implemented connection pooling, and fine-tuned garbage collection.
