Psychometrician & People Analytics Consultant

People data you can act on.

I help HR and talent teams validate their assessments and surveys, so hiring, engagement and retention decisions rest on evidence, not guesswork.

The problem

You already collect people data. The question is whether you can defend it.

01

Your hiring test has no evidence it predicts performance, or that it is fair.

02

Your engagement survey produces scores nobody knows how to act on.

03

Your people dashboard reports numbers, but not the decision behind them.

That is the gap I close: the scientific layer between people data and people decisions.

How it works

Simple process. No black boxes.

You bring the decision and the data. I bring the method, the evidence and a clear answer.

01

Send the context

Your instrument, survey or dataset, and the decision you are trying to make.

02

I audit and analyze

Reliability, structure, drivers, fairness or prediction, whatever the decision requires.

03

You get a verdict and a plan

A plain-language answer, the evidence behind it, and the actions that follow.

04

We implement

Optional dashboard, scorecard, presentation or follow-up support.

Most projects start with a 30-minute fit call NDA available by default
Selected work

Real problems, clear decisions.

Two samples of the work: one on selection quality, one on listening at scale. Both use public or synthetic data.

Sample projects · public or synthetic data · client work is confidential

A single view of candidate fit, cognitive performance and selection quality, built to help recruiters see what the data is telling them.

Voice of customer & exit interviews

Themes, sentiment and priorities from open-ended responses, so the loudest voice is not the only one that gets heard.

Confidentiality

Your data stays yours.

People data is sensitive by definition. Every engagement starts with confidentiality, not as an afterthought.

  • NDA available by default.
  • Access limited to the people who need it.
  • Only the minimum data required for the decision.
  • Project files deleted when the work is done.
