Experience

    Exoplan

    Founding engineer

    An energy-aware calendar for iPhone and Apple Watch, made with designer Paul Never. I was the only engineer.

    • Built the model that turns 8 weeks of Apple Health data into a daily energy estimate for each person.
    • Built the AI assistant that drafts your schedule. It asks the iPhone for your live calendar and energy data before it answers.
    • Built the sleep score: it cleans up Apple Health sleep data and rates each night against your own last 30 days.

    A “marketplace of help” for Ukrainian refugees and people in need.
