About this gig
Majority of AI voice agent gigs list every platform they have touched, hoping one name matches your search. That tells you nothing about whether it will work.
I build AI voice agents in Vapi, Retell, or Synthflow, connected to ElevenLabs for natural voice, set up around your call flow, not a generic demo script with your business name swapped in.
What You Get:
Custom AI agent in Vapi, Retell, or Synthflow, whichever fits Natural voice via ElevenLabs Flow scripted around your business, not a template Testing before handoff Documentation, no lock-in
Why Work With Me:
I pick the platform based on your needs Clear communication about what is realistic.
Simple Process:
- Send your call flow or use case
- I recommend a platform and build it
- You test and request changes
- I hand off a working agent plus docs
I am relatively newer to Fiverr, but not new to these tools.
Message me your use case and let us find what fits.

I build AI voice agents and receptionists using Vapi, Retell, Synthflow, and ElevenLabs, matched to whichever platform actually fits your use case rather than whatever I happen to default to. A lot of business owners don't know which platform they need, they just want a phone agent that works, handles real questions, and doesn't fall apart the moment a caller says something unexpected.
My focus is a working system built around your actual call patterns, with honest expectations about what an AI voice agent can and can't handle yet, not inflated promises about day-one perfection
FAQ
Which platform will you actually use — Vapi, Retell, or Synthflow?
Whichever fits your use case best; I'll recommend one based on your call flow and budget, not default to whichever I prefer.
Do I need my own API keys/accounts for these platforms?
Yes, you'll need your own Vapi/Retell/Synthflow and ElevenLabs accounts; I build within them, I don't resell platform access.
Will the agent handle unexpected questions well?
It handles what's scripted and reasonably adjacent questions; genuinely open-ended conversation is a real limitation of current voice AI, not something any honest builder can fully solve yet.
Do you provide ongoing support after delivery?
Absolutely.
