Muhammad R.

I build AI-powered phone systems: voicemail drops, call routing, transcription, and voice agents on FreePBX, Asterisk, Twilio, and SIP trunks. My last client’s AI voicemail system (BulkVS + Whisper + GPT-4o) earned a 5.0 review after 264 hours of work.. I specialize in OpenAI-powered automation, VoIP/SIP applications, API & webhook integrations, and cloud deployment along with front-end and back-end procedures. I help businesses restore broken workflows, prevent system failures, and keep applications running smoothly. Most of my work involves: Debugging systems that broke due to API key changes, third-party updates, or deployment issues Designing reliable, maintainable automation (not fragile scripts) Integrating multiple services using documented APIs and webhooks Deploying and maintaining apps on AWS/VPS environments What I specialize in: OpenAI / AI-powered systems (prompting, TTS, automation) API & webhook integrations VoIP & SIP-based applications (BulkVS, VoIP.ms, voicemail systems) Node.js / MERN frontend/backend development Cloud deployment, debugging & redeployment Machine Learning and Python Ongoing maintenance & monitoring Recent work highlights: Built and maintained an AI-personalized voicemail drop system using OpenAI, TTS, SIP trunking, and AWS Diagnosed and fixed production issues caused by rotated API keys and service changes Redeployed and stabilized systems after long inactivity periods Coordinated with clients to ensure smooth handover and future-proofing 🧩 How I work I first identify the root cause, not just patch symptoms I communicate clearly and kindly—no technical overwhelm I aim for long-term reliability, not quick hacks If you’re looking for someone who can take ownership of your system, fix what’s broken, and keep it running smoothly—let’s talk.
