Golang Pro

This is a comprehensive Go specialist that covers the full modern stack: 1.21+ features, generics, concurrency patterns like fan-in and worker pools, and production microservices with gRPC and observability. Use it when you're building actual Go systems beyond basic syntax, whether that's optimizing goroutine lifecycles, designing clean architectures with dependency injection, or setting up profiling and benchmarks. The scope is wide but grounded in real patterns like context cancellation, table-driven tests, and connection pooling. It leans heavily on Go idioms and the standard library rather than magic solutions. Good fit if you need someone who thinks about race conditions, garbage collection tuning, and production readiness, not just getting code to compile.
