Choudhry S
About this gig
Your business misses calls every day. Each one is a lost booking or a lost lead. I build AI voice agents that answer every call 24/7, talk naturally with callers, and book appointments directly into your calendar.
I have built production voice agents for real businesses, including an AI receptionist for an accounting firm handling 3 appointment types with reschedule and cancel flows, and a booking agent for a dental clinic. These systems take live calls today.
What I build for you:
- AI voice agent / AI receptionist on Retell AI or Vapi
- Inbound call answering with natural conversation
- Appointment booking with Cal.com, Calendly, or GoHighLevel calendar integration
- Reschedule and cancel handling
- Lead qualification and ai cold calling flows
- SMS confirmations and CRM sync via n8n automation
- Premium voices with ElevenLabs
Why me instead of a template seller: I am an infrastructure engineer. I build the full pipeline behind the agent, including webhooks, APIs, and error handling, so your agent does not break when a caller says something unexpected.
Note: Retell/Vapi/Twilio usage costs are billed on your own accounts.
Message me before ordering and I will map your call flow for free.

I build and run GPU and LLM infrastructure, on-prem and in the cloud. I wrote IaC for GPU cluster orchestration on KAUST Shaheen III, the Middle East's #1 supercomputer (2,800 NVIDIA GH200s). Real results: vLLM latency cut from 3.2s to 800ms, monthly cloud bill dropped from $10K to $4K, LLMs served to 1,000+ concurrent users on bare-metal Kubernetes with zero downtime for 12 months. Stack: vLLM, Triton, GPU Kubernetes (bare-metal and GKE/EKS/AKS), Terraform, Ansible, Ray, Kubeflow, RAG, voice agents. I run a dual RTX Pro 6000 server at home. On-prem GPU work is my daily reality.

FAQ
Do I need my own Retell AI, Vapi, or Twilio account?
Yes. I build and configure everything on your accounts so you keep full ownership and control. You pay usage costs (per-minute rates) directly to those platforms. I will guide you through account setup — it takes about 10 minutes.
How much do the platform usage costs run per month?
Typically $0.05–$0.15 per call minute depending on platform and voice choice. A small business handling 300 calls monthly usually spends $30–80. I will help you pick the most cost-effective setup for your call volume.
Which calendar systems can you integrate?
Cal.com, Calendly, GoHighLevel, and Google Calendar. The agent checks real availability live during the call, books the slot, and sends confirmation. Reschedule and cancel flows are available in the Premium package.
Can the agent handle callers who go off-script?
Yes, that is the point of my build approach. I add fallback logic, clarification prompts, and graceful handoff to a human number when needed. I test edge cases before delivery so the agent does not break on unexpected questions.
Can you build outbound / cold calling agents too?
Yes. I build outbound agents for lead qualification, appointment setting, and follow-up calls. Note that outbound calling has legal requirements (TCPA in the US, consent rules elsewhere). You are responsible for calling compliance in your region.
What do you need from me to start?
Your business details, FAQ answers or knowledge docs, calendar access, and platform accounts. I send a short intake form after order. Standard package needs about 30 minutes of your time total.
Can I hear a demo before ordering?
Yes. Message me and I will share a live demo number you can call and test yourself. I can also do a video consultation to map your call flow before you order.
Will I be able to edit the agent myself afterward?
Everything is on your accounts, so yes. If you want a guided handover, the Training extra includes a 60-minute session teaching you to edit prompts, voices, and flows without me.
