600 seems low - I earned a lot more than that back in the day, and that was a long time ago. A quick search of jobserve.com for just "java" found roles quoting up to 750 on the first page, and if you're any good that'll be negotiable. And if you get into even slightly niche things (Oracle Coherence, in my case) the rates are much higher.

I don't think it's very far from the reality of your full stack app developer though.

Ie. 900+GBP/day is listed rarely and for very specific/niche things.

Then, the more niche it is the more likely it is that the downtime between contracts becomes longer I imagine.

Curious what your anecdotal experience has been, to the extent that it can be shared.
