Project structure for backend "CQRS" services

Given that project covers multiple business domains (Shipping, Warehousing, User, Authentication, Accounting, etc) and each of domains consists of multiple services:

• Shipping
  -- REST/gRPC API GW
  -- WebSocket GW
  -- Command Service
  -- Event Handler Sevice
  -- Denormaliser Service
  -- Query Service

I need to think how to structure those services. Main target is to achieve service isolation so that single team/person could work on it without navigating over whole repository and it should be deployable as single unit. At the same time code sharing and package reuse should be heavy accepted. All those services should be scoped to its domain/sub-domain.
