HIPAA-aware AI voice agents for healthcare — built on Synthflow, Retell AI and ElevenLabs. I turn missed calls into booked appointments with 24/7 reception, appointment booking and CRM automation that capture every inquiry and route it into your real systems. I specialize in production voice agents (Synthflow, Retell AI, Voiceflow, ElevenLabs) wired into your real systems — GoHighLevel, HubSpot, EHR / booking tools, Twilio telephony, plus AI chat & WhatsApp assistants (ManyChat, WATI) — with OpenAI / GPT-4o driving the conversation and n8n / Make orchestrating the workflow end to end. Healthcare is where I'm strongest. Recent work includes: Patient growth & booking across a 55-clinic chiropractic network (Australia) 24/7 AI shift-coordination for UK NHS healthcare staffing Bilingual (EN / ES) after-hours patient reception (Miami) Inbound AI receptionists for dental & medical clinics AI voice agent for medical consults (Synthflow + PracticeQ / EHR) I design with compliance in mind: HIPAA-aware architecture, PHI minimization, audit logging, and clear medical-escalation rules — the AI never diagnoses or gives medical advice; it routes to your staff. Beyond healthcare, I deliver the same voice + integration stack for clinics, agencies, startups, and appointment-driven service businesses. What I deliver: AI voice & chat agents: inbound / outbound calls (Twilio, VoIP), WhatsApp & web chat, FAQ, triage, appointment booking Lead qualification, enrichment & conversion bots Knowledge-base & RAG assistants (document / data retrieval, multi-agent) AI automation for business operations (n8n, Make, Zapier) + API / webhook integration CRM & calendar integration (GoHighLevel, HubSpot, Google Calendar) QA & testing for conversation flows and backend logic Backed by 8+ years in project management and backend development (JavaScript, Node.js, Express, serverless, Supabase), I own the full delivery cycle — architecture, conversation design, QA, deployment.
