Building maintainable systems: what we standardize at Techxagon

Good code is maintainable code. Here are our standards.

**Code quality:**

- Consistent style (linters, formatters)
- Meaningful variable names
- Comments explain "why" not "what"
- DRY principle (Don't Repeat Yourself)

**Testing:**

- Unit tests for business logic
- Integration tests for API endpoints
- End-to-end tests for critical user flows
- Test coverage metrics (aim for 80%+)

**Deployment:**

- CI/CD pipelines for automated testing and deployment
- Staging environment that mirrors production
- Rollback procedures
- Blue-green or canary deployments for zero-downtime

**Documentation:**

- README with setup instructions
- API documentation (OpenAPI/Swagger)
- Architecture diagrams
- Runbook for common operations and troubleshooting

**Why this matters:**

New developers can onboard quickly. Bugs are caught early. Deployments are predictable. Systems can scale without breaking.

Code that works today but can't be maintained tomorrow is technical debt. We build for the long term.
