Senior FullStack Web and Mobile App Developer VoIP Infrastructure Specialist
Hi, I'm Zarachtech. With years of experience bridging the gap between complex telecommunications and modern web architecture, I help businesses build scalable, high-performance digital infrastructure....
About this Gig
Are you looking for a reliable, high-performance telecommunications setup for your business?
Whether you need a custom Asterisk dialplan, a complete PBX system built from scratch, or troubleshooting for your existing VoIP architecture, you are in the right place.
As a Senior Full-Stack Developer and VoIP Infrastructure Specialist, I bridge the gap between complex telecommunications and modern web architecture. With over 100+ successful VoIP projects completed, I ensure your voice systems are secure, scalable, and crystal clear.
What I Can Do For You:
- Custom Asterisk Development: Dialplans, IVR (Interactive Voice Response), and routing logic tailored to your exact business needs.
- SIP & Trunking Setup: Seamless configuration of SIP trunks, softphones, and gateways.
- Call Center Solutions: Queue management, call recording, agent dashboards, and CRM integrations.
- PBX Installation & Configuration: FreePBX, Issabel, VitalPBX, and custom Linux/Unix server deployments.
- Troubleshooting & Auditing: Fixing one-way audio issues, dropped calls, SIP registration errors, and server security audits.
FAQ
What do you need from me to get started on my project?
To begin, I will typically need your server access details (SSH/root credentials for your Linux/Unix server), information about your SIP trunk provider, and a clear description or flowchart of how you want your call routing (IVR or dialplan) to work. If you aren't sure, just message me.
Can you integrate my Asterisk/PBX system with a web application or CRM?
Yes! Because I am also a Senior Full-Stack Web and Mobile App Developer, I don't just set up the telecom side. I can help bridge your VoIP infrastructure with third-party APIs, custom web dashboards, or CRM platforms to make your call center run smoothly.
Do you provide ongoing support after the project is finished?
Absolutely. I provide documentation for the custom solutions I deploy, and I am available for remote connection support to ensure everything is running perfectly after delivery. If your business requires long-term maintenance or monitoring, we can set up a custom ongoing monthly gig.
