Magento Code Audits & Cleanup

Magento Code Audits & Technical Debt Reduction

Over time, Magento stores accumulate technical debt—outdated code, unused extensions, and quick fixes that become permanent problems. Our Magento code audits identify issues and create a roadmap for improvement.

What We Audit

Custom Code Quality

We analyze all custom modules and theme code for:

• Coding Standards: PHPCS/PHPMD compliance, PSR standards
• Best Practices: Proper use of dependency injection, service contracts
• Security Vulnerabilities: SQL injection, XSS, CSRF risks
• Performance Issues: N+1 queries, missing indexes, inefficient loops
• Deprecated Code: Usage of deprecated Magento APIs

Database Health

• Table sizes and growth trends
• Index usage and missing indexes
• Orphaned data from deleted entities
• Log table bloat (customer_visitor, report tables)
• EAV attribute efficiency

Extension Assessment

• Identifying unused or redundant extensions
• Code quality of third-party modules
• Update status and security patch levels
• Performance impact of each extension

Theme Architecture

• Proper inheritance and fallback structure
• JavaScript module organization
• CSS/LESS efficiency and specificity
• Layout XML best practices

The Audit Deliverable

You receive a comprehensive report including:

1. Executive Summary: High-level findings and risk assessment
2. Detailed Findings: Each issue with severity, location, and explanation
3. Recommendations: Prioritized list of improvements
4. Effort Estimates: Time/cost estimates for each fix
5. Roadmap: Suggested phasing for cleanup work

Common Cleanup Tasks

Legacy Code Removal

We safely remove:

• Unused modules and their database tables
• Dead code paths and commented code
• Obsolete customizations from past requirements
• Duplicate functionality across modules

Database Optimization

• Archiving old orders and quotes
• Cleaning log and report tables
• Optimizing catalog_product_entity_* tables
• Removing orphaned EAV values

Code Refactoring

• Converting class rewrites to plugins
• Implementing proper service contracts
• Adding missing unit tests
• Improving error handling and logging

Ongoing Code Health

After cleanup, we can implement:

• Automated code quality checks in CI/CD
• Regular database maintenance scripts
• Quarterly mini-audits to prevent debt accumulation
