Here are answers to some earlier questions, so my situation may become a bit more clear:

“Tell us more about what you want to do.”

It didn’t seem on-topic to mention goals and such in my original query, so here is a short list of software goals and answers to a question above:

    creating a “killer app” :  Since the 80’s. many many tries.
     was lucky enough to work on CineLook for several years,
 
    synesthesia: the merging and mixing of different types of media : this has been a fixation of mine for decades

    making UI’s that look good AND are easy to use

    data visualization:  good data visualization can really help 

    game development: my first app that sold was a math game

. . .

“Do you have anything you want focus on or do you pride yourself on being a generalist?”

It seems to me that AR will become the de facto standard for UI/UX, and most software will need to adapt to that new metaphor. That includes multimedia and musical software. It would be great to help out in that area somehow. In the 90s I wrote lots of in-house tools, which required me to think like a generalist. This sort of work is fine for me but I would place it as a second priority desire in a perfect world.

. . . “Architect, team lead, or pure development of a system from day to day?” Have led a team on a few occasions and was able to handle it but it would depend on the team. Have done pure development for decades but it doesn’t have to be the only thing I do.

. . .

“And business domains that you’re especially familiar with or interested in?”

Anything involving new uses of media and trans-media. Some things being done in aerospace are very appealing, such as the concept of a 3D-printed rocket. Financials are interesting also, as would be supporting research in astronomy, physics (especially superconductivity) or perhaps infrastructure. Education is also a great field to do work in.

thanks once again for all the info and support!
