You will get Production-Grade Voice AI Agent & Custom AI SaaS Architecture
Project details
Most AI agents that get demoed never survive production. As a specialized AI Developer, I engineer production-grade AI systems that do calling real customers via an autonomous Voice AI Agent, executing multi-step business logic with a custom AI Agent, and shipping cleanly as scalable AI SaaS applications.
I provide end-to-end AI SaaS Development and advanced AI model integration utilizing a robust tech stack: Python, Node.js, Next.js, FastAPI, and Supabase.

Build MVP1 AI Voice Receptionist (Twilio + OpenAI) for Plumbing Company
Usama was responsive, technically capable, and worked through a complex Twilio-based flow with care and persistence. He was open to feedback and stayed engaged through testing and refinement. I appreciate the effort and collaboration.

About Usama
AI Voice Agents That Turn Missed Calls Into Booked Appointments

Job Success
Taxila, PakistanĀ - 2:11 pm local time
I build production-ready Voice AI agents that answer your phone 24/7, qualify leads, book appointments, and turn missed calls into booked revenue without you hiring another receptionist.
I have built and deployed voice agents across home services (plumbing, HVAC, roofing), healthcare (clinics, dental, patient scheduling), and general appointment-driven businesses. Different industries, same problem: calls come in when no one's there to answer, and that's money walking out the door. I fix that.
šš”š² šš®š¬š¢š§šš¬š¬ šØš°š§šš«š¬ š°šØš«š¤ š°š¢šš” š¦š šØšÆšš« šØšš”šš« šš šš šš§šš¢šš¬:
š¹ My voice agents run at as low as 3 cents per minute often lower than what you will pay just for the base platform on Vapi, Retell, or similar third-party tools, before you even add your LLM and telephony costs. Lower cost per call means the ROI math works from day one, not just at scale.
š¹ Real deal-closing conversations, not scripted IVR. My agents handle objections, qualify leads properly, and book directly into your calendar or CRM they don't just šš§š¬š°šš« šš§š šš«šš§š¬ššš«.
š¹ Proven scale I have helped take an AI automation operation to $1M+ in the last 3-4 months, so I know what it takes to go from ššØšØš„ ššš¦šØ to šššš®šš„š„š² š«š®š§š§š¢š§š š¦š² šš®š¬š¢š§šš¬š¬.
What I build:
š¹Inbound & outbound voice agents (booking, qualification, objection handling, call transfers)
š¹Missed-call-to-lead recovery systems (instant callback/SMS follow-up when a call is missed)
š¹CRM & calendar integration (GoHighLevel, HubSpot, Zoho, Calendly, and more)
š¹Multilingual agents where needed
š¹Automation layers connecting voice agents to your existing tools (n8n, Make, Zapier)
If you are a plumber losing after-hours jobs to voicemail, a clinic drowning in no-shows and missed appointment calls, or any business where every unanswered phone call is a lost customer let's talk. Send me a message and tell me what's breaking in your operations; I will tell you honestly whether a voice agent fixes it.
