What types of projects do you prefer to use Go for? Microservices architectures, or CLI tools and system programs? What do you prioritize most: performance, simplicity, or concurrency capabilities? Why do you make this choice?

Yo, I've always seen Go as the dynamo of microservices. Last year, I had to develop multiple APIs and transaction engines for a DeFi project. I started with Node.js back then, but as soon as I pushed the event loop, I kept hitting performance bottlenecks. A friend suggested, "Why not try Go?" So, I rewrote the microservices in Go as a weekend project. Result? A task expected to take a week was done in two days, and CPU usage dropped by half.
Same story with CLI tools. I've been working with Ethereum nodes for a while now, and I often need custom analysis scripts. Thanks to Go's built-in concurrency model (goroutines + channels), I can process block data in parallel and generate reports. And simplicity? Third-party dependencies are minimized, and being able to handle everything with just the standard library is a breath of fresh air. Honestly, I haven't seen another language where performance and simplicity mesh together this well.
For Go, I mostly rely on backend services that handle high loads, especially in the microservices area. That's where the strengths of the ecosystem shine—easy parallelism with goroutines and high-performance network operations really come into play.
I also often build small CLI tools or DevOps scripts in Go, especially when I need static binaries and fast execution. For me, the simplicity of the toolchain and the clean syntax matter more than raw performance here.
