I've had subcontracting roles like this in the past. Still not zero interaction, but if you build a network of strong people and you're known for getting shit done, what I've found is other developers that know and trust you are more than happy to subcontract work out to you, and that tends to be very low-overhead from an interaction perspective. The last time I did this, I had zero contact with the actual customer (which can be a downside to be honest sometimes); the dev with the contract and I would just sync up so I knew what I was supposed to be doing and I would just go off on my own and get it done, then we'd sync up for the next thing, rinse and repeat. In my experience, as long as you get along really well with the other dev(s), this is pretty close to what it sounds like you're looking for. But this does require building up a network of people who are willing to subcontract you out work, which isn't always easy.
