Hello.
First of all, I am so excited to find such a high technical project.
As you can check on my profile, I have over 2 decades of web/mobile app developing experience.
So far, having done tons of projects, I get deep knowledge in these fields including PHP, Asterisk PBX, Network Administration, Linux and VoIP.
Now I am free to work and available at any time and I can meet your timeline with the best work.
Looking forward to hearing from you.
Thanks for considering me.
