How did cross-team collaboration occur during integration with other services?

Cross-team collaboration when integrating with other services is usually based on clearly defining APIs, protocols, and communication channels. In the context of Golang and microservices architecture, this may include:

• Using REST or gRPC for data exchange between services.
• Sharing contracts (e.g., OpenAPI specifications) to agree on request and response formats.
• Regular meetings and synchronization between teams to discuss changes and plan integration.
• Using version control systems and CI/CD for coordinating releases.
• Implementing monitoring and logging for quick detection and resolution of issues.

In practice, for example, the team responsible for the authentication service provides a well-documented API, and the team developing the frontend or another service uses this API. When changes are made to the API, teams coordinate changes through pull requests, reviews, and communication in chats or issue trackers.

Thus, successful cross-team collaboration is built on transparency, documentation, automation, and constant communication.
