Hi! I am Maksim from Ukraine (UTC +2)
We worked with Facebook API and messaging the site via Facebook is an interesting task for us. Also, we finished one project two days ago and we are ready to start urgently.
We work with cms WordPress and such technologies as HTML, CSS, JavaScript, Bootstrap, MySQL and PHP.
If it works for you I will be happy to set up a short call with to discuss all technical details.
Kind regards,
Maksim
