AI Voice Agent Developer | Retell AI, n8n & GoHighLevel | Claude | A2P

Are missed calls, delayed follow-ups, and manual lead qualification costing you high-ticket clients? In industries like Real Estate, Healthcare, Insurance, and Construction, speed to lead is everything. Every unanswered call or delayed text is money left on the table. I build AI-driven infrastructure that ensures your business responds instantly, qualifies intelligently, and books automatically - 24/7. My background isn't in traditional software development; I am a licensed Civil Engineer. Why does that matter to you? Because I don't just "connect apps." I approach AI and automation with an engineering mindset. I design robust, fail-proof digital infrastructures with solid foundations, contingency plans (retry-logics, API error handling), and scalable architecture. Your AI systems need to be as reliable as a physical structure, and that is exactly what I build. How I transform your operations: ☑️ AI Voice Receptionists: Building advanced conversational agents using Retell AI and ElevenLabs that don't just sound human, but understand context, handle objections, and navigate complex scheduling constraints. ☑️ Intelligent Lead Qualification: Deploying text and voice agents that ask the right questions, verify data (DNI, pricing, status), and route high-value leads directly to your human sales team. ☑️ Seamless CRM Architecture: Integrating AI deep into GoHighLevel (including complex API v2 integrations), ensuring every conversation is logged, tracked, and synced with your sales pipeline. ☑️ Compliance & Reliability: Ensuring complex workflows meet industry standards, including A2P 10DLC compliance for SMS outreach and timezone-aware logic for global clients. 🧠 The Tech Stack I Master: Retell AI | n8n | GoHighLevel (GHL) | Make .com | Zapier | OpenAI | Claude | Gemini | WhatsApp APIs | Supabase | Twilio | CRM Expert Why partner with me? 💡I specialize in helping U.S. and European businesses bridge the gap between cutting-edge AI and practical business operations.
