I built a custom web app for my wife.
She uses Adwords all day long and there mapping tool for radiuses sucks, so I wanted it to be easier for her.
She ended up letting her co-workers use it too, and they love it.
It has copy and paste functionality so that you can save the custom map and open it later.
Today, one of her co workers accidentally emailed a link to this custom web app to a client. He opened the link, and declared it to be the best thing since sliced bread.

Unfortunately, not my client, not my job ... so, it really doesn’t mean much for my career. But it did make me feel good.
Thinking maybe create account functionality and start selling subscriptions. Could be a few extra bucks a month. Lol.
