Go Coffeeshop
go-coffeeshop is an event-driven microservices architecture designed to manage the end-to-end lifecycle of customer orders. It coordinates independent services using asynchronous messaging patterns to handle business workflows, background processing, and order fulfillment tracking.
The project utilizes a HashiCorp stack for infrastructure, employing Nomad, Consul, and Vault for service orchestration and secret storage. Infrastructure is managed through declarative automation using Terraform to ensure consistent and repeatable deployment of compute resources and networking.
The system includes a REST API gateway for traffic routing and a service mesh for secure internal communication. Technical capabilities cover compile-time dependency injection, type-safe query generation, and the use of protocol buffers for code generation.
Functional areas cover digital product inventory management, menu retrieval, and the processing of customer orders from placement through to final fulfillment.
