Science gives us clarity, but product work gives it purpose.
Psychologist · Psychometrician · Product Leader · Data Scientist
I'm a psychometrician and product designer with a PhD in social cognition who spent twenty years in the lab studying how people think — then started building products that use that science. Think of me as a human translator between science and product — curious by default, never fully satisfied with easy answers.
Problems I solve — as an independent consultant or through my companies
Career quizzes, competency batteries, personality instruments, cognitive ability tests — designed with IRT and CTT, validated before deployment. Plus the scoring and matching systems that make results actionable. Used by LSEG, EPAM, and HSE Ireland.

See SWPSPsychometrics, product consulting, growth engineering, and statistical modeling sit on the same page because they run on the same engine: measurement, systems thinking, and turning fuzzy human problems into testable product logic. The gap between "we think this works" and "we measured that this works" is where most products fail — and where all of this work lives.

How I approach problems — the methodology, the results, and what I learned
"I'm not a developer. I'm a psychologist who builds products. The science disappears into the product — that's the point."
Things I started, run, or helped build from the ground up
AI as CTO · infrastructure from scratch · psychometrics in production · growth systems · rigorous experimentation
Two structural equation models from two custom psychometric studies converged on the same finding: tenure predicts two specific traits and nothing else. What that means for high potential employee program design and HiPo development.
Two custom psychometric studies in different industries, run on different instruments, recovered the same four workplace personality types. What that convergence means for L&D budget allocation and employee development planning.
Three-layer WordPress server monitoring: a self-healing cron healthcheck that auto-restarts services, a diagnostic status dashboard, and an external Telegram bot for downtime alerts and disaster recovery.
