If you have Ph.D. in bioscience and you've done custom data analysis, is this a possible niche that you can pursue? Is it something that you would want to pursue? Or do you want to leave bioscience behind completely?

If you are interested in software development, then creating specialised software for a particular domain or field might be a path worth pursuing.

You have deep knowledge of a specialised subject (bioscience) which puts you in a unqiue position to identify possible opportunities. Are there common tasks that bioscience professionals do regularly? Could you produce softawre that optimises those tasks? What software is used in the industry? Do you think you can do better from what you've seen or used? Ask yourself how you would make it better? What would convince others to use your software? Is there something you can produce that would make things easier or more productive for people working in bioscience? Do you think bioscience companies would be willing to pay for your software or services?

I realise these aren't answers to your questions, but I think they are some of the questions you should consider thinking about. Good luck!
