AI Calling Agent Specialist

May 2026 - May 20260 mos

I build outbound AI calling systems for businesses that need faster lead follow-up, better qualification, and fewer missed sales opportunities. My work focuses on AI calling agents that can contact leads, hold natural voice conversations, ask qualification questions, handle objections, and warm transfer interested prospects to a live sales rep. These systems are built for teams that want more consistent outreach without relying only on manual calling. I work with Retell AI, Vapi AI, Twilio, ElevenLabs, Deepgram, OpenAI, webhooks, and CRM integrations. Most projects include custom prompt writing, call flow design, transcript delivery, lead status tracking, and handoff logic based on the outcome of each call. Typical work includes: outbound AI cold calling agent setup lead qualification call flows warm transfer to a human sales agent Twilio voice integration Retell AI and Vapi AI configuration call transcript and summary delivery CRM sync with Google Sheets, GoHighLevel, or other tools webhook automations for follow-up workflows prompt optimization for natural voice conversations I have built AI voice solutions for agencies, local businesses, sales teams, and service-based companies that need quick response times and scalable call handling. My focus is simple: build AI calling systems that can perform in real sales workflows, not just test demos.
