I was the only engineer. - Built the energy model, a Python function on Firebase that turns 8 weeks of HealthKit heart rate, activity and sleep data into daily energy estimates. - Cut out workouts and dropped outliers with DBSCAN, then fitted a LOWESS curve for each weekday, with a threshold that adapts to each person. - Built an AI scheduling agent over WebSocket that asks the iPhone for live EventKit and energy data through tool calls before it answers. - Scored each night’s sleep against the person’s own 30-day baseline, after cleaning up the HealthKit sleep data.
