How I Implement CI/CD

cicd

1

Idea and Design ✅

Phase:

  • • Discussion of business requirements.
  • • UX/UI designers create mockups (Figma, Adobe XD).
  • • Functional requirements and user stories are defined.
  • • Discussion of technical implementation with the team.

🎯 Outcome:

  • • Design mockups.
  • • Technical specifications.

2

Development ✅

Phase:

  • • Development of functionality in a separate feature branch.
  • • Code review (Pull Request, Merge Request).
  • • Automatic CI process execution (testing, static analysis).

🎯 Outcome:

  • • The final code passes review and is merged into develop or staging.

3

QA Environment (Testing) ✅

Phase:

  • • Code is automatically deployed to the QA environment.
  • • Unit tests, integration tests, and end-to-end tests (Jest, Cypress) are executed.
  • • Manual testing by QA engineers.
  • • Bug fixes if necessary.

🎯 Outcome:

  • • QA engineers approve ("OK") or return the code for revision.

4

Staging (Pre-Production) ✅

Phase:

  • • Code is deployed to staging (pre-prod).
  • • Performance and security testing.
  • • Final approval from business/product managers.

🎯 Outcome:

  • • Code is ready for production ✅.

5

Production Deploy ✅

Phase:

  • • Code is deployed to main or master.
  • • Automatic deployment to production (AWS, Vercel, DigitalOcean).
  • • Service stability check after release (health checks, monitoring).

🎯 Outcome:

  • • Code is live on production! 🚀

6

Monitoring and Support ✅

Phase:

  • • Logging and monitoring (Sentry, Datadog).
  • • User behavior analysis (PostHog, Google Analytics).
  • • Hotfixes in case of critical issues.

🎯 Outcome:

  • • Quick response to issues.

7

Product Maintenance and Growth ✅

Phase:

  • • User support (customer service).
  • • Development of new features, bug fixes.
  • • Data analysis, A/B testing implementation.

🎯 Outcome:

  • • The product is evolving and improving.

Automated CI/CD Process ✅

Phase:

  • • Push to feature-branch → Automatic tests 🚦
  • • Merge into develop → Deployment to QA 🌍
  • • Merge into staging → Pre-production review 💡
  • • Merge into main → Production deployment 🚀

CI/CD Tools:

  • • GitHub Actions / GitLab CI / Jenkins (CI)
  • • Docker + Kubernetes (Containerization)
  • • AWS, Vercel, DigitalOcean (Deployment)
  • • Sentry, Datadog (Monitoring)
