* I work with pretty niche enterprise devops software. My Linkedin profile is 100% oriented to selling my skills with that software (Note that there is a real risk that this software will be out-of-fashion in five years)

* I give a proper reply to everyone who contacts me on LinkedIn, even if the work they are offering is totally unrelated to what I can/want to do. The frequent spam is a small price to pay in return for being in everyone's database.

* I'm very upfront with my day-rate and get rejected by most of the recruiters/companies that get in touch with me because it's too high. This is fine and intentional because there is enough demand to get that rate anyway (so far).
