Behavioural data,
made legible.

I'm a data analytics postgraduate in London. I build leakage-clean predictive models, interactive behavioural analysis tools, and reports that stay honest under scrutiny — because a number only helps if it survives the audit.

Featured work

Two projects, one standard.

Every piece here is built on data I can defend: documented sources, audited pipelines, and results I can reproduce.

HF-RISK — Predicting Heart Failure Outcomes with Machine Learning

A leakage-clean pipeline on 2,008 patients comparing five models. XGBoost reached 0.710 AUROC at six months; SHAP explains the cardiorenal axis it learned — and 0.599 transfers to MIMIC-IV without retraining.

Interactive Card Sorting — Spatial Organization & Cognitive Strategy

Given cards — and sometimes blanks — on an 8×8 board, how do people organise what matters? 845 recorded trials show organisation beats raw effort, and blank cards act as scaffolding. Live explorer for retry tracing.

Capabilities

What I actually do.

Four moves, repeated carefully: model, clean, explain, report.

  1. Predictive modelling

    Regression, survival models, tree ensembles — benchmarked honestly, with baselines.

  2. Data quality

    Missingness audits, leakage hunting, and feature hygiene before any model sees the data.

  3. Explainability

    SHAP-driven reduction and calibration checks, so stakeholders can see why a model says what it says.

  4. Reporting

    Board-ready dashboards and static reports that separate signal from confidence theatre.

Approach

Three principles I don't bend.

  1. 01

    Integrity before performance

    A high AUROC built on leaked features is a liability, not an achievement. I audit first, then report what survives.

  2. 02

    Explainability is the deliverable

    A model nobody can question is a model nobody can trust. SHAP, calibration and honest failure modes are part of the work.

  3. 03

    Small is honest

    With 2,008 patients or 845 trials, I report what the data can actually support — and say plainly when that's a limit.

Let's build something insightful together.
