Naresh K.
AI Voice Agent Developer | Inbound, Outbound, Appointments
I build AI voice agents that answer your calls and make outbound calls for you. **Inbound** The agent picks up every call, including after hours. It answers questions, books appointments against your real availability, sends the confirmation, and transfers to your team when a human is needed. Every call gets logged in your CRM. -Real estate: asks about budget, area and timeline, then books the viewing. -Clinics: handles booking, rescheduling and cancellations, and puts clinical questions through to staff. -Home services, dealerships, salons, restaurants: the phone gets answered when your team cannot pick up. **Outbound** -Calling new web enquiries within a minute of the form being submitted. -Qualifying leads against your criteria so your sales team only speaks to the good ones. -Calling old leads in your CRM to re-engage and rebook them. -Appointment setting, follow ups, no-show recovery, renewal and payment reminders. *Common requests* -24/7 receptionist -Booking, rescheduling, cancelling -Lead qualification before a rep gets involved -Reactivating an old lead database -Answering repeat questions from your own documents -Call transfers with context -Automatic call summaries into your CRM **Why hire a developer for this?** No-code tools get you a demo in an afternoon. The problems come later: the voice sounds robotic, the agent talks over the caller, it fails when someone goes off script, and it has no proper handoff to a human. I have 8 years in software development and the last 2 focused on voice agents. I handle the full setup: phone number and telephony, voice quality, calendar and CRM integration, human handoff, and compliance for outbound calling. **Engagement options** Starter (1 to 2 weeks): one agent, one use case, live on your number and connected to your calendar. Full build (3 to 5 weeks): multiple call types, inbound and outbound, team transfers, knowledge base from your documents, and a dashboard with call logs and outcomes. Audit and fix: you already have an agent that is underperforming. I review the recordings, identify the issues, and fix them. **Tools** Vapi, Retell, LiveKit, Twilio, ElevenLabs, Deepgram, OpenAI, Claude Code, GoHighLevel, HubSpot, Salesforce, Calendly, n8n. I recommend based on your call volume and budget. **Track record** Top Rated on Upwork, 100% Job Success, 100+ projects delivered, 8,000+ hours logged. Tell me what happens when a call comes in and nobody is available, or how many leads you have sitting uncalled. I will tell you if a voice agent makes sense for your situation and what it will cost per call. First 30 minutes free. Click "Invite to Job" to get started.
