Neil Kandalgaonkar

Hacker, maker of things

I’m happiest in a place that respects
kindness, enthusiasm, and individuality,
doing many kinds of work,
(mostly writing internet software,
but also design, writing, & leadership),
serving a clear and inspiring goal
that creates more value for others than ourselves.
