About this gig
Your Vapi or Retell agent talks over callers, loses the thread or breaks when it calls a tool? I'll fix it, or build a new one the right way.
FIX AND TUNE AN EXISTING AGENT
- Rewrite the prompt so it stays on task and sounds natural
- Fix interruptions, long pauses and awkward turn taking
- Repair broken tool calls, webhooks and transfers
- Tune voice, model and transcriber settings for speed and cost
BUILD A NEW AGENT
- Custom Vapi or Retell agent for inbound or outbound calls
- Custom tools: check availability, book, look up orders, create records
- n8n or Make workflows for CRM, Sheets, Airtable, Slack and email
- Post-call summaries and data sent where you need it
HOW IT WORKS
1. Share your agent or use case and what is going wrong
2. I test it with real calls and send a short findings list
3. I fix or build, then retest the same calls
4. You get a change log and a walkthrough video
WHY ME
I'm a UX designer who builds. I treat every call as a user flow, so my fixes improve how the call feels, not only the settings.
Send me a call recording or describe the problem and I'll tell you what I'd fix first.

Hi, I'm grams, who builds AI voice agents that answer, qualify and book calls for small businesses and agencies. I work in Vapi, Retell and GoHighLevel, and connect agents to your calendar and CRM with n8n or Make.com. My design background shapes the process: I map the call flow first, write a script that sounds like your team, then test real calls with you before handover. Expect fast replies, clear updates and a walkthrough video of everything I build. Need inbound, outbound, GHL or a fix for an agent you already have? Pick the gig below or message me your use case today.
FAQ
Vapi or Retell: which should I use?
Both work well. Retell is often quicker to set up for standard receptionist flows; Vapi gives more control over tools and custom logic. I recommend one after hearing your use case.
Can you work on my existing agent?
Yes. Invite me to your workspace, or share the agent settings and a few call recordings. I test before changing anything and log every change.
