While others build simple "zaps," I architect enterprise-level ecosystems that combine the front-end power of GoHighLevel (GHL) with the back-end stability of Red Hat OpenShift and Azure. I bridge the gap between "marketing automation" and "IT infrastructure," ensuring your AI Voice Agents and Chatbots are hosted in secure, containerized environments with 99.9% uptime and automated disaster recovery. Core Technical Stack: Automation & AI: Advanced n8n/Make.com workflows integrated with AI Voice Agents and custom LLM chatbots for lead-to-cash lifecycle management. Infrastructure as Code (IaC): Leveraging Ansible to automate server provisioning, configuration management, and application deployment across hybrid environments. Cloud & Containerization: Architecting scalable clusters on Red Hat OpenShift and Microsoft Azure. Expert in Linux (RHEL) hardening and management. CRM Strategy: Full-stack GoHighLevel engineering, including API integrations, custom snapshots, and SaaS-mode optimization. Governance & Security: Implementing enterprise-standard Backup & Storage solutions and CI/CD pipelines to ensure data integrity and rapid deployment. The Value I Bring to High-Ticket Projects: Reduced Overhead: I use Ansible and Linux to self-host automation (n8n), saving you thousands in monthly SaaS subscription fees. Enterprise Scalability: Using OpenShift, I ensure your AI infrastructure scales automatically as your traffic grows. Stability: Your systems are built with failovers and automated backups—no more "broken workflows" halting your revenue. "I don't just connect apps; I build the infrastructure that scales companies." 收起
