Five things you can open and click, not just read about. Every screenshot below goes to the running version.

• 

  GridShift

  Learns where the New York grid’s day-ahead forecast goes wrong, then picks the cleanest four-hour window for a compute job. The scheduler on the page is the real thing, running over seventy-one held-out days.

  RetentionLab

  Calibrated churn scores turned into a call list a retention team could actually work — ring the riskiest fifth and you reach half the churners. The model answering here is the one the repo tests.

  SMB Growth Intelligence

  GA4 events through layered ETL, a point-in-time feature store, a propensity model and a data-quality engine. CI runs the whole pipeline on every push and publishes whatever it produced — the wall time on the page changes run to run because it is real.

  Forecasting Baselines

  Naive, moving average, Ridge, XGBoost and an LSTM benchmarked walk-forward on sixteen years of real market data. None of them beat “tomorrow = today” on RMSE, which is the correct result — and the headline says so rather than burying it.

  Geometry Dash RL

  DQN, PPO and a genetic algorithm trained in a headless simulator running four thousand times faster than real time, then dropped into the retail game through a C++ mod to clear a full official level.
