Commission custom User Defined Functions?

edited November 13 in General Discussion

Is it ok to post a request for a custom Vertica User Defined Function as a paid freelance job?
If able and interested can contact me directly with questions/quote. I'll update this post when hired.

EDIT Revised request below to extend an Collection function

I'd like a function APPLY_VARIANCE() such that works similar to other Vertica Collection functions, but returns the sample variance.

E.g. SELECT APPLY_VARIANCE(ARRAY[1,2,3,4]); would return the sample variance, 1.666667

Reading the docs, it seems that these could be created as a scalar User Defined Functions in C++. While these functions are documented and I used to know C++ well in the past, it seems like it would be way faster and better to hire someone already experienced with writing UDFs in Vertica.
