To be clear I was saying 105k for senior, and more than that for staff/principal.

As to day rates I think it's rather about companies willing to pay a bit more to get better contractors rather than any specific stack.

London day rates I've seen for contractors are more like 700 - 900/day on average at places that pay a bit better and 1000+ for specialists. And base salaries I've seen advertised for senior developers at funded startups (e.g. Wagestream, Truelayer) are more like 105k now (more for higher levelings - i.e. Principal/Staff).
