I build data systems that ship.

The kind that pay for themselves. Models that keep the accounts worth keeping, aim spend at the customers who convert, and stop losing tests before they cost a quarter. Thirteen live labs below. Click anything.

Each card opens a working model. Move the sliders, watch the economics change.

FIG. 01

Churn Model

Finds the customers about to leave. Saves revenue already paid to acquire.

Customer Segmentation

Sorts customers by value. Aims spend at the 21% who generate 64% of revenue.

Recommendation Engine

Guesses what they'll watch next. Every basis point of watch-time is a subscription renewed.

A/B Test Simulator

Shows when a "winning" version is real and when it's noise. Stops losing tests early.

Bayesian + frequentist · adjustable priors

Funnel Simulation

Finds the one customer segment quietly killing conversion without breaking the rest.

Sketch Recognition

Draw anything on the canvas. A small AI model running on your laptop guesses what it is, in real time.

Model Picker

Ask in plain language: "cheapest model good at code." Get a side-by-side comparison of the four AI models that fit.

AI & Jobs

Type your job. See how exposed it is to AI and to robotics, and what the BLS projects through 2030. The two pressures hit opposite ends of the workforce.

Time-Use Atlas

How Americans actually spend 24 hours, drawn as a clock. Pick an age, an employment status, or a parenting situation. Watch the day redraw.

Algorithm Watchdog

A daily-refreshed read on what YouTube's algorithm is rewarding right now. Video length, posting times, category mix, channel concentration.

AGI Horizon

Two hundred fifty AGI predictions plotted on the year they were said and the year they targeted. The future has been "twenty years out" since 1965.

250 predictions · 140 figures · 1950 → 2026

Logistic Regression

The simplest classifier worth deploying. Plant points on the canvas. Watch gradient descent slide a probability boundary into place, live.

The Model Atlas

An expert system over 13 discriminative ML models. Five questions about your problem, one recommendation with reasons, and a deep live demo for every destination.

13 models · 5 questions · ~150 lines of decision rules

Dirty data,
clean production.

End-to-end builds, not slideware. Each one shipped with the plumbing, the UI, and the deploy. Usually that's three teams and two quarters of work. Below is what happens when one person owns it.
