Migrating microservices from Node.js to Go

[ SYSTEM LOG: 2025-08-20 ] At SpinnrTech, we faced a bottleneck with our order tracking API written in Node.js. Under high concurrency, the event loop struggled with CPU-intensive data transformations. I led the initiative to rewrite this specific microservice in Go. Results: - Memory footprint reduced by 60%. - Response time dropped from 120ms to 15ms. - Concurrency handled gracefully with Goroutines. Node.js is still my go-to for I/O heavy, rapid prototyping, but Go's performance in CPU-bound microservices is unmatched.
