Voice AI Specialist | GoHighLevel, N8N, Retell, Twilio, Eleven Labs

Hi, I’m Siti. I’ve deployed 160+ AI Voice Agent across industries. As a System Integrator specializing in Voice AI, I build production-ready systems for clients far beyond Upwork, including agencies, service businesses and founders worldwide. If you’ve moved past the 'cool demo' phase and need a Voice AI system that truly scales, I am the technical bridge you’ve been looking for. My approach is simple: I listen first. The technology (Vapi, Retell, ElevenLabs, N8N) is just the engine. What truly matters is your business goal... more leads, fewer missed calls, higher conversions, smoother operations. I treat every project not just as a job, but as a true partnership. You deserve clarity, reliability, and predictable outcomes. We start by ensuring we’re always aligned on expectations and direction. From there, I dive deep into your workflow and CRM to identify bottlenecks, designing a system that not only delivers measurable results but also sounds natural. 👇 Why I'm the Right Choice for Your Team ◾️ I speak your Language (and Your CRM's): I work closely with platforms like GoHighLevel, so I deeply understand the day-to-day needs of agencies and small businesses. I know exactly what needs to happen to move a lead from the AI call right into your pipeline. ◾️ The System Has to Work: My background is in systems integration. That means I don't just set up the voice AI... I handle all the messy back-end stuff (the API calls, conditions and logic) and make sure everything is talking to your CRM perfectly. No more data silos. Just a synchronized system. ◾️ Speed for Success: I can build and deploy the initial version of your system fast. This is key, because the real work starts when the system is live. I use that real-world feedback to quickly make the improvements that matter, getting you to a truly reliable, production-ready solution sooner. ◾️You Are the Expert, I Am the Guide: You know your customers best. I know the technology best. You bring the insight, I bring the systems. Together, we choose the right tools… whether that’s Retell AI, GHL’s native Voice AI, or another stack, based on what truly serves your calls, your workflow, and your budget. What's the most advanced, genuinely useful use case you've built? I get this question a lot... and one of my favorite systems to build is a multi-calendar, multi-user Voice AI scheduling system. This is especially powerful in service industries like medspas. Let me give you a real example... A medspa might offer multiple treatments and have several practitioners. And as you probably know, medspa clients often have a favorite specialist, someone they trust, someone whose work they’re willing to pay extra for. But here’s the problem... When customers call, most systems only allow a general appointment. They can’t choose the exact service or their preferred practitioner, which leads to frustration and lost revenue. So I built a Voice AI system that fixes all of this. The agent can: ✔ Understand the service the client wants ✔ Check availability across multiple calendars ✔ Match the booking to the client’s preferred practitioner ✔ Offer alternatives if that practitioner is full ✔ Confirm, reschedule, or cancel appointments automatically ✔ Follow up after bookings when needed It feels natural, personalized, and completely aligned with how customers actually book in the real world. And the best part is that it runs fully on its own, a true hands-off Ai agent that takes over the work your front desk team normally handles. 📞 Let's Get Unstuck and Moving: Building AI systems can feel complicated, but it doesn't have to be. Outside of Upwork, my agency provides consultation and training, and I'm here to support you or your development team with any AI/CRM integration challenges.
