"Maybe there's a small but reasonably profitable endeavour out there" I am actually thinking about just this. Let's see.

I started working on recording meetings and converting the recordings to meeting minutes with actionable items. Not a trivial task. My idea was to build an iPhone app with ML in the cloud. I did some initial market survey and found no takers for this idea. I spoke to startups, mid-enterprises and even law firms. I got one positive response from a VC who said this could be useful in tracking the meetings he has with founders as most of them go untracked but I was not too convinced (perhaps I was wrong). So dropped that idea and tried on some ideas around computer vision, prompted by the problems some of the customers were elucidating to while validating the above idea. "We don't really care about meetings but can you use machine learning to monitor people ? I am not a big fan of surveillance. After this I have drifted quite a bit around the last year or so. Current situation - no direction. Just having a side thought on doing something around high definition maps. Looked for a job to fill up some savings, but boy the interviewing phenomenon is nuts. I haven't interviewed in like 15 years. So got back to doing leetcode and Hackerrank.

Hmm, Wagepoint. I was involved in vetting the younger of the two to the older. They both had similar interests and the experience of the older complemented the energy and enthusiasm of the younger.

I don't have a current website yet. Thanks for pointing this out. I have a static page at callindra.com (works without the www) I have to fix the Godaddy DNS. Will do.
