The Cognitive Data Science Lens

Each piece here applies cognitive science principles to data and AI challenges. This isn't just technical writing—it's a systematic exploration of how human cognition shapes (and should shape) the systems we build.

📚

Canon: Foundational Frameworks

Start here. These pieces define my approach to data, AI, and system design.

CANON

Vision, Perception, and Data Viz for Decision-Making

Why great charts aren't pretty—they're perceptually efficient. Using preattentive cues, luminance over hue, and small multiples to answer one question per view.

Bees, Graphs, and Governance

How treating beehive photos as a knowledge graph revealed universal patterns for enterprise data governance. Sometimes the best systems emerge from the messiest domains.

RAG Without the Theater

Evidence-linked retrieval patterns you can defend. Skip magic prompts; use small, testable patterns that tie claims to sources.

Why Your Dashboards Fail: A Cognitive Scientist's Perspective

The 200-millisecond problem, working memory limits, and why humans don't want data—they want narratives. With examples from my fitness tracker redesign.

Data Stories: Cognition in the Wild

Real projects where cognitive principles meet messy reality.

The Choco Effect: How a Dog Transformed My Running Data

When my running data collided with dog walks, it revealed how consistency beats intensity—and how life's interruptions make better data stories than perfect tracking.

From Owl Box to Data Pipeline: A Beekeeper's Digital Journey

How 400+ unlabeled bee photos became a knowledge graph using EXIF metadata, weather APIs, and computer vision. A masterclass in finding structure in chaos.

Building & Learning in Public

Technical journeys, lessons learned, and works in progress.

IoT Sensor Fleet: From Arduino to Analytics

Building a temperature sensor network taught me that real-time data is only valuable if humans can understand it in real-time too.
