    I am a Senior System Administrator and VoIP Engineer with over 7 years of expertise in deploying and managing Class 4-5 Grade VoIP Softswitch platforms such as PortaOne and VoIPSoft-Switch, as well as hosted PBX systems, including both multi-tenant and stand-alone setups. My core competencies include VoIP systems based on Asterisk (e.g., FreePBX, AsteriskNOW, Issabel, Elastix), Freeswitch (e.g., FusionPBX), Grandstream UCM, and Linux environments (CentOS 7, Ubuntu). I also have extensive experience with 3CX solution design. In addition to my VoIP skills, I have a strong background in networking, particularly with firewalls and security solutions. I am skilled in configuring and managing Fortigate, Sophos, and SonicWall firewalls to ensure secure and optimized network performance. I excel in designing complex call routing using 3CX Call Flow Designer, creating interactive IVR systems with database integrations, and managing cloud services like MS 365, Azure, and AWS. My certifications in VMware Data Center Virtualization (vSphere 6.7) and Red Hat further strengthen my capabilities in virtualization and system optimization. Throughout my career, I have led various large-scale projects, including deploying a 2000+ user mail server using Zimbra and Postfix, implementing data center virtualization, and deploying VoIP platforms using Elastix and FreePBX for banks and IT companies. I hold a Bachelor’s degree in Electronics and Telecommunication and a Master’s degree in Computer Science.

My rate maybe higher than others but i can assure you that I can deliver any work satisfaction guaranteed!
