You will get CRM Solution integrated with an IPPBX system (Click to call and pop-up)
I had the pleasure of working with Tanvir on a recent project, and his assistance was invaluable. Despite the project extending beyond the initial timeline due to payment issues from Upwork itself, Tanvir's expertise and knowledge about Issabel and the Vtiger Solution were evident throughout. His deep understanding of these platforms significantly contributed to the progress and eventual success of our project. I highly appreciate his efforts and would recommend his services to anyone looking for an expert in Issabel and Vtiger solutions.

Job Success
Dhaka, Bangladesh - 8:18 pm local time
I specialize in combining telephony infrastructure with modern AI technologies to create intelligent, scalable systems — including conversational IVR, voice bots, and automated call workflows.
My expertise includes:
• Asterisk, SIP/PJSIP, WebRTC, IVR systems
• AI voice pipelines (STT → LLM → TTS)
• Conversational AI & smart call routing
• Backend systems, APIs, and CRM integrations
• Cloud deployments (AWS, DigitalOcean, Linux)
I have built and deployed production-grade systems used in enterprise and high-volume environments, focusing on performance, reliability, and scalability.
I also actively use AI-assisted development tools (ChatGPT, Claude, etc.) to accelerate development, debug complex systems, and improve code quality.
