Custom Code Audit

Security vulnerability analysis of custom modules. Performance bottleneck identification in custom code. Code quality and maintainability assessment. Best practices compliance and patterns.

Technical Debt Assessment

Identification of technical debt and its business impact. Quantification of maintenance cost increases from debt. Prioritisation of debt reduction investments. Strategic roadmap for long-term code quality.

Performance Analysis

Code profiling identifying bottlenecks and inefficiencies. Database query analysis for N+1 patterns and inefficiency. Observer and plugin overhead assessment. Memory usage and leak identification.

Security Review

Vulnerability analysis against OWASP Top 10. SQL injection and XSS prevention verification. Authentication and authorisation implementation review. Data protection and encryption assessment.

Database Schema Review

Schema efficiency and query optimisation potential. Index strategy assessment and improvement recommendations. Normalization and denormalization analysis. Backup and recovery capability assessment.

Testing Assessment

Current test coverage analysis and identification of gaps. Test quality and effectiveness evaluation. CI/CD pipeline review and improvement recommendations. Testing strategy recommendations.

Audit Scope

Quick Audit: 1-2 week engagement reviewing specific areas. Suitable for targeted review of extensions or features. £5,000-£10,000.

Standard Audit: 2-4 week comprehensive review covering architecture, code, and performance. Suitable for most businesses. £15,000-£25,000.

Enterprise Audit: 4-8 week deep-dive including infrastructure, security, and strategic recommendations. Suitable for large complex platforms. £30,000-£50,000+.

Our Code Review Approach

Preparation

Define audit scope and objectives. Gather documentation about system architecture. Access repository and development environments. Establish review criteria and benchmarks.

Analysis

Review custom code against best practices. Analyse installed extensions and their compatibility. Profile performance and identify bottlenecks. Scan for security vulnerabilities. Assess technical debt.

Testing

Unit test coverage analysis. Integration test verification. Performance test execution. Security test scanning for vulnerabilities.

Documentation

Create audit report with findings and recommendations. Document identified issues with severity assessment. Provide improvement recommendations with effort estimates. Suggest architectural improvements.

Recommendations

Prioritise recommendations by impact and effort. Create implementation roadmap. Estimate costs and effort for improvements. Plan strategic improvements.

Common Findings

Architecture Issues

Monolithic design preventing scaling
Missing service contracts and dependency injection
Plugin and observer overhead
Hard-coded values instead of configuration

Performance Issues

N+1 database queries
Missing or inefficient indexes
Unoptimised collection loading
Cache invalidation problems

Security Issues

SQL injection vulnerabilities
Cross-site scripting (XSS) prevention gaps
Weak authentication or authorisation
Unencrypted sensitive data

Technical Debt

Duplicate functionality across extensions
Poorly documented code
Lack of test coverage
Outdated dependencies

Scalability Issues

Database bottlenecks limiting scale
Caching strategy gaps
Infrastructure constraints
Third-party API rate limiting

Typical Audit Findings

Priority 1 - Critical: Security vulnerabilities, data corruption risks, system stability threats. Address immediately.

Priority 2 - High: Performance issues impacting revenue, technical debt reducing maintainability. Address within 1-2 months.

Priority 3 - Medium: Code quality improvements, maintainability enhancement. Address within 3-6 months.

Priority 4 - Low: Nice-to-have improvements, code aesthetics. Address when time permits.

Better security posture (vulnerabilities fixed)
Increased team velocity (better code quality)
Reduced technical debt (cleaner codebase)

Sample Audit Questions

How much technical debt exists and what's its business impact?
Are we following Magento best practices and coding standards?
What's our test coverage and where are the gaps?
Are there security vulnerabilities or compliance risks?
Could our architecture scale 10x without major redesign?
Where are the biggest performance bottlenecks?
Are we using extensions efficiently or creating redundancy?
What improvements would give us the best ROI?

Code Quality Benchmarks

Best in Class: 80%+ test coverage, <5% technical debt, follows all best practices
Good: 60-80% test coverage, 5-10% technical debt, follows most best practices
Average: 40-60% test coverage, 10-20% technical debt, mixed best practices
Poor: <40% test coverage, >20% technical debt, inconsistent practices
