I build AI receptionists, AI voice agents and call center systems on Twilio, SignalWire and SIP. They answer calls, qualify callers, book appointments and warm-transfer to your team, with SMS follow-up and CRM sync. I have 7+ years in VoIP and have built 4 call-tracking systems that run in production. Most voice AI projects break on the phone side: SIP routing, transfers, caller ID, compliance, SMS follow-up and CRM sync. That is where I'm strongest. What I build: - AI receptionists and voice agents on Twilio Voice with OpenAI GPT-4, Whisper and text-to-speech - IVR, call routing, queues, TaskRouter, recording and transcription - Outbound dialers with answering machine detection (shipped in production), click-to-call and call analytics - SMS/MMS automation: 2-way follow-up, outbound MMS with replies and CRM sync (built for a law firm) - WhatsApp Business API messaging synced to HubSpot and Salesforce - FreeSWITCH in production (about 1 year) Projects I've delivered: - A call-tracking SaaS built end to end on Laravel and SignalWire: IVR builder, call/SMS/voicemail tracking, multi-ring, call forwarding, recordings, email reports and payments - A live answering and virtual receptionist system on Twilio and SignalWire for a US business, running in production today - Laravel and Vue full-stack web apps, dashboards and restaurant POS integrations (Clover, Lightspeed, Toast, Square) How I work: - Every account (Twilio, SignalWire, OpenAI, CRM) stays in your name - Scripted test calls before go-live, plus documentation at handover - Based in Pakistan (UTC+5), with regular US-hours overlap Stack: Twilio, SignalWire, FreeSWITCH, SIP, Python, Laravel/PHP, Vue/Nuxt, Livewire, MySQL/PostgreSQL, AWS, OpenAI. Send me your call flow and I'll reply with the stack I'd use and a fixed quote.
