Shipping Secure Authentication in One Day: The Hidden Power of AI-Assisted Code Review

Comprehensive AI-assisted code review identified 10 critical vulnerabilities that would have shipped to production, proving that rigorous review is not a luxury but essential infrastructure. By combining security-first design, automated testing, and multi-angle AI analysis, the author demonstrated that 'building right' paradoxically saves time compared to shipping fast and patching later. This approach becomes increasingly critical as AI tools enable detailed code analysis at scale.
