You could try join a proven startup like DropBox or AirBNB etc. They should be able to give you a good salary and equity and there is still scope for it to go up.

Or you can foray into sales, or CTO role at your smallco. Then as a director negotiate shares.

However sounds like you'd be good as a technical cofounder. You said "I can learn anything in no time" and it sounds like you are ambitious.

You could also launch a lifestyle business like many on HN have done, which can slowly grow to beyond what a dev could earn in a job.
