AI at scale: production risks and onboarding

(04:00) Brought to you by Unleash

Unleash is a private, flexible, and scalable feature flag system that lets teams decouple deployments from releases. It reduces the risk of shipping new features and gives organizations real-time control over what reaches production. And as AI accelerates development, Unleash helps engineering teams move fast and stay stable with safe rollouts and instant kill switches. Start a free trial of Unleash at ⁠getunleash.io/pricing⁠.

Why do so many software projects still fail despite modern tools? The answer often lies in the psychology of the team, not the technology stack.

Software development is often viewed purely as a technical challenge, yet many projects fail due to human factors and cognitive bottlenecks. In this episode, Adam Tornhill, CTO and Founder of CodeScene, shares his unique journey combining software engineering with psychology to solve these persistent industry problems. He explains the concept of “Your Code as a Crime Scene,” a method for using behavioral analysis to identify high-risk areas in a codebase that static analysis tools often miss.

Adam covers the tangible business impact of code health, specifically how it drives predictability and development speed. He explains why 1-2% of our codebase accounts for up to 70% of our development work, and how focusing on these hotspots can make our team 2x faster and 10x more predictable. Adam also provides a critical reality check on the rise of AI in coding, exploring whether it will help reduce technical debt or accelerate it, and offers strategies for maintaining quality in an AI-assisted future.

Key topics discussed:

• Combining psychology and software engineering
• Why predictability matters more than speed
• Treating your codebase as a crime scene
• Behavioral analysis vs. static analysis
• The hidden danger of the “Bus Factor”
• Will AI help or hurt code quality?
• Why healthy code helps both humans and AI
• Essential guardrails for AI-generated code
