Bias Detection Tools Are Only as Good as Your Data Model

Bias detection tools identified only 34% of bias issues I encountered in production. The other 66% originated in data modeling decisions upstream of any tool's reach.

AI Ethics Certification Is Credential Theater Without Engineering Practice

AI ethics certifications test knowledge of principles but ethical AI requires engineering discipline. I found zero correlation between certification and practice quality across 9 organizations.

Event Sourcing as Organizational Memory

An event-sourced system maintained 2.8 million state changes over 3 years, enabling state reconstruction at any point in time and reducing audit preparation by 83%.

Ethics of AI in Hiring: Algorithms That Gate Opportunity

Four AI hiring systems embedded discriminatory patterns through architectural choices affecting 2.3 million applicants annually. The discrimination was not intentional. It was architectural.

Emotional AI and the Boundary of Machine Perception

Emotion detection accuracy ranged from 62-78% for basic emotions and 31-45% for complex states across 3 systems. Classifying surface patterns is not perceiving emotions.

On Building Things That Last in a Culture of Disposability

We live in a culture of disposability. The average system is deprecated within 7 years. Wabi-sabi and Stoic durability offer a counter-philosophy: build for endurance, not novelty.

Python’s Gravity Well: Language Choice Shapes Architecture

Python is present in 92% of data pipeline codebases, creating path dependencies that constrain infrastructure for years. Its gravity well requires strategic, not revolutionary, escape.

Data Privacy Engineering Is a Data Engineering Discipline

Implementing tokenization and differential privacy at the pipeline level reduced PII exposure incidents by 89% while adding less than 3% to processing time.

The OKR Trap: Why OKRs Break at Scale

OKRs created 312 person-hours of overhead per quarter at a 120-person org. The framework fails when used to create alignment rather than represent it.

The architecture of a second brain that actually works
