Freelancer profile translated to English.

Description

I am a telecommunications engineer.

I was among the top 10 engineers in my class.

Since 2008, for 12 years, I have specialized in everything related to Voice over IP (VoIP):

I master the signaling protocols (SIP, IAX, H323, RTCP, WebRTC) and the details of each.

I master the most popular VoIP software such as Asterisk, FreeIPBX, Kamailio, OpenSips, a2billing, Hylafax.

Of course, IP networks and the configuration of dozens of brands of routers, switches and modems are my daily work.

I have worked for 3 major Telecom operators in France, and I designed 80% of their Wholesales termination platform.

I was a team leader for the development of an IPBX from A-Z with all the VoIP and Billing functionalities, also the integration of fax and the automatic configurations of IP phones according to their brand. Now, this IPBX is the most popular nationally.

I was also the team leader of the VoIP part of the CRM project: so I have excellent experience of everything that is predictive, clictocall, call center, IVR, Voicemail, SMS, emailing, statistics....

I often use PHP, Shell scripting, Mysql, Java, virtualization.

I have used several security and supervision tools such as: Squid, OpenFire, OpenSwan, Iptables, Smokeping, Zabbix, Munin, Nagios, Fail2ban, Whireshark...

My time is very precious. So, when you choose me, you can expect the work to be done in the short term and perfectly. I don't like doing something that doesn't need to be done.
