Alternates open type

Needing an experienced programmer familiar with the calt (contextual alternates) feature

Basically, the situation is that I am in need of a programmer with the skill necessary to program fonts by integrating the calt OpenType feature into them. I am more than willing to be taught these skills, as I will be creating multiple fonts utilizing this feature and possibly some other advanced ones. If anyone is interested and believes they are capable of such a task, please contact me at thepcnerd7@gmail.com. I highly appreciate any advice or input, and thank you for your time and willingness!

Issue with contextual alternates

Forums: 

Hello,

I'm currently working on a type project that requires some opentype knowledge that I lack.

I would like to create a font that use contextual alternates to swap glyphs based on there occurence in the text.

Therefore the font would have to "count" the number of time a letter appear in the text and switch it if need be.
For exemple I'd like to be able to set an opentype feature that would swap the 25th "a" and 3rd "b" of the text with an alternative "a'' and "b". I'd like the font to be able to evolve depending on the content used and select additional letters based on the number of time that letter was used.

Is there a way to do something like that ?

I'm fairly new to font creation and open type features but I have some basic knowledge of Glyphs and Robotfont.
