Integration & Deployment

Streamlined CI/CD pipelines and deployment strategies

Development

The development workflow integrates various technologies to ensure code quality, collaboration, and efficient delivery of features.

Feature Development

Developers work on features using TypeScript for frontend (React) and Java/Spring Boot for backend services.

Version Control

Code is managed in GitLab repositories with branch-based workflow and merge requests for code reviews.

Code Review

Team members review code changes for quality, security, and adherence to architectural patterns.

Automated Testing

Unit tests, integration tests, and end-to-end tests verify functionality across the microservices.

Local Development

Docker Compose enables developers to run the entire system or specific services locally for testing.

Continuous Integration

GitLab CI runs automated builds and tests for every code change to catch issues early.
