If you’re quite experienced in a certain tech (nothing special, for example just Rails) 150+ is quite doable even subcontracting or on long 6mos+ engagements where you don’t worry much about finding clients

I subcontracted for about 6mos with a late stage startup at closer to the 100/hr rate, then negotiated up to closer to 150 for the next 6

I wasn’t doing anything special, literally just another dev on a given team just without benefits and without having to attend company events or having a boss

And this was my first ever contracting engagement too (was all fulltime before that)
