Zero to Hero: How we make great Golang engineers at Luno
summary
Luno’s onboarding turns non-Go hires into idiomatic Go engineers by having them build a toy service that runs a customer→service→supplier→worker flow over gRPC and an asynchronous state machine, using company tooling like the open source reflex and heavy use of go:generate. The process emphasizes idempotency, error-as-value tracing, consistent zero-value and parameter conventions (context first), and practical gotchas to avoid: shadowing, nil maps, pointer copies, goto and fragile iota enums.
