Matt Kandler

iOS Developer / UX Designer / Full-stack developer / Brooklyn, NY /

Crafting online experiences designed to delight on every screen.

I’m an interface designer and full-stack developer who started out studying mechanical engineering and robotics. I believe better designs are often simpler designs. Fast iteration trumps pixel perfection. Shipping and learning is more important than waiting and launching. Always talk to users, but the user isn’t always right.

These days I’m working as a full-time engineering role at 🏃‍♀️Runhouse🏠, a tool for AI/ML development, with nights & weekends on Happyfeed 😊.
