Overview

Code review services provide expert code analysis for companies needing security audits, technical due diligence for acquisitions, code quality assessment, or external code reviews.

You review codebases identifying security vulnerabilities, code quality issues, technical debt, architectural problems, or performance bottlenecks, providing detailed reports and recommendations.

Success requires deep development expertise across languages and frameworks, security knowledge, ability to assess architecture and scalability, and communication translating technical to business.

Pricing includes project fees for code audits ($3,000-25,000 depending on codebase size), hourly consulting ($150-350), security audit services, technical due diligence for investors/acquirers, or retainer for ongoing code review.

Projects involve accessing and analyzing codebase, running security scanning tools, manual code review for quality and security, assessing architecture and scalability, documenting findings and recommendations, presenting results to technical and business stakeholders, and potentially providing remediation support.

Startup costs include security and analysis tools, courses and security certifications, demo projects for portfolio, professional liability insurance, and marketing totaling $3,000-12,000.

Building client base involves partnerships with investors and M&A advisors (technical due diligence), targeting startups raising funding (code audits), security-focused content marketing, cold outreach to companies experiencing security issues, and showcasing expertise through certifications and technical writing.

Revenue comes from audit project fees, hourly consulting, security assessment services, technical due diligence for deals, and potentially remediation development work.

Operating costs include security and analysis tool subscriptions, continued learning and certifications, professional liability insurance, marketing, and potentially subcontractors for large projects.

Challenges include accessing client codebases requires trust, conveying findings diplomatically, liability if missed vulnerabilities, clients may not act on recommendations, and limited ongoing relationship after audit.

Success requires deep technical expertise across languages and frameworks, security certifications adding credibility, excellent technical writing and presentation, balancing thoroughness with business priorities, and potentially specializing in specific languages, frameworks, or industries.
