About this gig
Do you need a powerful AI Voice Agent that actually works in real business workflows?
Youre in the right place. I build real, production ready AI systems using Retell AI, VAPI, n8n, Zapier, Make.com, and more.
I help businesses automate calls, qualify leads, route conversations, update CRMs, send SMS follow ups, and remove manual work completely.
If you want an AI that speaks, listens, thinks, and acts I will build it.

FAQ
What do I need to get started?
Just tell me your use-case. If you already use Retell AI or Vapi, share your API key, if not, I will guide you through setup.
Can the AI voice agent follow a custom script?
Yes. I will customize the script to match your brand tone, questions, and workflow. The agent will respond intelligently, not just read a script.
Do you integrate the agent with CRMs or other apps?
Absolutely. I can connect the agent to CRMs, Google Sheets, webhooks, or your automation tools (n8n/Make.com) so all data flows smoothly.
Will I be able to test the agent before final delivery?
Yes. You will get a test call or demo to validate the voice quality, responses, workflow, and integrations before the final handover.
