Islamabad, Pakistan - 7:14 pm local time
I specialize in Full Stack, AI voice agents for real businesses, not demo bots. Each AI voice agent I build is designed to answer inbound calls, make outbound follow-ups, understand caller intent, collect the right information, qualify leads, book appointments, summarize conversations, update your CRM, and transfer to a human when needed.
If your business islosing revenue because calls are missed, follow-ups are slow, appointment booking is manual, or your CRM is disconnected from your call flow, I can help you build a Full Stack, AI voice agent that works inside your real business workflow. My Full Stack, AI voice engineer work makes sure that agent is not just talking, but recovering revenue, routing leads, updating systems, and triggering follow-ups.

How I Work
Before building a Full Stack, AI voice agent, I map the full customer journey:
1. Caller intent and call flow
2. Conversation logic and qualification questions
3. AI voice prompt engineering and fallback paths
4. Appointment booking or lead capture flow
5. CRM fields, tags, and pipeline stages
6. SMS, email, WhatsApp, and calendar follow-ups
7. Human handoff logic
8. Post-call summaries and CRM updates
9. Real call testing and optimization
10. Documentation and handoff
A strong Full Stack, AI voice agent should not just talk. It should understand intent, collect the right information, qualify the lead, book the appointment, update your CRM, trigger follow-ups, and escalate to a human when needed.
