I stumbled upon some of the Indie Hackers podcasts and liked them a lot. I like the idea of building helpful products for a niche market that could generate a reasonable income for one or two people.
I have worked as a developer for many years: https://www.linkedin.com/in/michael-katz-69840b/
I'm currently consulting about half time on emergency response software for NOAA.
On the side, I have made some games for iOS and Android.
I have a number of web-based ideas I'm working on, a mix of for-profit and just-for-fun projects.
