I will build a production ai voice agent and receptionist
Zsombor Horvath
About this gig
Your phone rings, the lead goes to voicemail, and the sale walks. I build AI voice agents that answer every call 24/7, sound genuinely human, and book the appointment before the caller hangs up.
I'm a software engineer building production systems on VAPI and Retell. That means an agent that holds up with real callers, not a demo that breaks on day two.
What I build:
- Inbound AI receptionists: answer, qualify, route, and book
- Outbound AI callers: lead follow-up, reminders, reactivation
- Real integrations: Google/Outlook Calendar, GoHighLevel, HubSpot, Salesforce, Airtable
- Natural voices (ElevenLabs), smart call routing, SMS/email follow-up
Perfect for clinics, law firms, real estate, home services, and agencies losing revenue to missed calls.
You get a tested, LIVE agent and a clean handoff not a black box. Every build ships with a live test call before delivery.
Message me with your use case before ordering and I'll tell you exactly what's possible and quote it. Let's get your phone answered.

Hi, I'm an AI engineer at Amazon who ships production systems, not demos. Besides creating traditional software systems (webapps, mobile apps), I also build custom AI agents, RAG chatbots grounded in your own data, and AI automations that hold up in the real world (LangChain/LangGraph, Claude, vector DBs, Python & TypeScript). Track record: a RAG platform with citations + hallucination control, an AI code-review agent that cut review time 80%, and web apps serving 6,000+ users. Message me and let's scope your project.

FAQ
Will the agent actually sound human, or robotic?
Human. I use premium natural voices (ElevenLabs) with tuned pacing, interruption handling, and natural fillers, so callers get a real conversation — not the choppy bots you've heard. You'll hear it yourself on a live test call before delivery.
Do you use VAPI or Retell?
Both — I pick the right one for your use case, and can use Synthflow or GoHighLevel if you prefer. I'll recommend the best fit when we scope the project, based on your call volume, integrations, and budget.
Can it connect to my CRM and calendar?
Yes. I integrate with Google/Outlook Calendar, GoHighLevel, HubSpot, Salesforce, Airtable, and most CRMs via API. The agent can book appointments, log calls, update records, and trigger SMS/email follow-ups automatically.
Are there ongoing costs after you build it?
Yes, and I'm upfront: voice AI has usage costs (telephony + AI/voice minutes) billed directly to your own account, usually a few cents per minute. My fee covers the build. I'll estimate your monthly cost before we start.
Can it handle both inbound and outbound calls?
Yes. Inbound receptionists (answer, qualify, route, book) and outbound callers (follow-ups, reminders, reactivation) are both covered. Standard includes one direction; Premium includes both.
What do I need to provide to get started?
Your use case and call goals/script, a phone number (or I'll help you set one up), and access to any tools you want connected. I'll send a short checklist after you message me so nothing slows the build.
Do I own it, and is there support after delivery?
You fully own your setup. Premium includes source code, documentation, and 14 days of post-launch support. I'm also available for ongoing maintenance or new features as a separate package.
