I'm currently working on a progressive web application for support workers in care homes. I've seen through first hand experience how much paperwork there is in this setting (daily outcome charts, medicine administration records, abnormal behaviour records, dietary and fluid intake, etc) and how many clerical errors there are. I've also seen first hand the key-document-dependency there can be around service user files, communication notification booklets for staff, etc, where changes often happen synchronously and are forgotten because the document isn't available in the moment. I've spent the last 4 months or so taking a sabbatical from working as a software engineer to work for £9.00/hour at a support home for people with mental and physical disabilities (think Down's syndrome or people who are unable to live in an independent setting). As a result I now know an awful lot about this setting, the people who work in this industry, the minimum feature set I would need and the legislative landscape these companies operate in. The best way to find a profitable side project is to become familiar with a none-technical discipline which is direly in need of modernisation. If you don't want to take time out of work, then choose an industry (it could be tree felling, red-brick manufacturing, shale oil extraction or solar panel installation) and figure out what the problems are plaguing the companies, staff or end customers. There are so many $1,000,000,000 companies out there just waiting to be founded in areas which are considered unsexy and don't involve yet-another-to-do-list application. Find one company, with one problem, fix the problem, there's your profitable side gig.
