You probably will not find a worthwhile project outside of your area of expertise. The market for "a guy who can code built a software for your industry" is pretty saturated now.
Unless you can split hairs on why specific products don't appeal to people in a given niche/industry, at the technical level that the users care about, you probably won't find much success.
In my personal experience I come from the medical side of things. The amount of garbage software written by people who know nothing about how we work is obnoxious. They all advertise themselves as the "next generation, streamlined, efficiency boosting" magic pill for us, but it's about as convincing as your 5 year old telling you they can do your taxes.
So my advice is find something to do in an area of expertise you already have.
