Thanks for the invite. I'm familiar with all the statistics you mentioned and know the CI calculation for most of them (will look up the details to refresh my memory). Most of these stats have a CI scaling with 1/sqrt(n) and the ratio ones need to be done on the log scale. e.g. for sensitivity and specificity, we have p +- 2*sqrt(p(1-p)/n) as the CI. I can code this in python, c++ or java.
