Best contact is e-mail. I have a g-mail account (jonathan dot a dot sherlock).
When I release code, I post it to the Traveller RPG Facebook group. Comments on those posts are read for suggestions and feedback.
Please report bugs! I test the code myself but there are always combinations I could not foresee.
I also love suggestions for future development. If it's not on my to-do list, you can put it on my to-do list.
Lastly, do you have your own application and wish you could take data from here? E-mail me and I will probably be able to get the data supplied in a format you want.
