AI SYSTEMS & AUTOMATION ARCHITECT FOR VOICE AI, RAG, GHL & CUSTOM MODELS.
Creator of the CEO Alignment Engine, omnichannel Voice and SMS pipelines, and custom fine-tuned models. I engineer high-reliability AI architectures across Google Workspace, GoHighLevel, n8n, FastAPI, and Kubernetes that eliminate bottlenecks without disrupting live revenue operations.
WHAT I ENGINEER & INTEGRATE
Voice and SMS agents, custom fine-tuned models, CRM integrations, and executive intelligence layers.
The CEO Alignment Engine
Connects Google Workspace (Gmail, Drive, Docs, Sheets), GHL CRM, and company databases into a single queryable layer. Gives leadership instant context, operational summaries, and decision support with exact source citations.
Voice, SMS & Mail AI Agents
Low-latency real-time voice agents using WebSockets and function calling, conversational SMS follow-ups, and automated email triage that qualify leads, handle intake, and route cleanly into your CRM.
Custom Model Training & Fine-Tuning
When prompt engineering hits its limit, fine-tuning takes over. Targeted training on your proprietary datasets, automated evaluation pipelines, and optimized inference endpoints for strict JSON output formats.
GoHighLevel (GHL) & n8n Ops Systems
Custom GHL setups built with automated AI qualification, n8n webhook orchestration, sub-account pipelines, and direct database sync for high-volume lead operations.
Google Workspace & Enterprise RAG
Turn Google Drive, Docs, Sheets, and internal files into a searchable vector index with strict document citations, semantic embeddings, and deterministic guards against hallucinations.
FastAPI, Docker & K8s (AWS / GCP)
Asynchronous Python backend services built with FastAPI, containerized with Docker, and deployed on AWS or GCP Kubernetes clusters for reliable, low-latency production uptime.
INDUSTRIES & OPERATIONAL USE CASES
Tailored AI systems, conversational voice/SMS agents, and executive intelligence layers engineered for high-transaction, high-trust operations.
Real Estate
Brokerages, Wholesalers & Property Management
Conversational Voice & SMS agents qualify buyers and sellers 24/7, sync property criteria directly into GHL pipelines, and query MLS/listing archives via semantic RAG.
Engineered Systems

Insurance
Agencies, Brokers & Independent Producers
Streamline policy intake, quote requests, and claims triage. Voice and SMS systems handle initial screening, collect underwriting criteria, and automate follow-ups.
Engineered Systems
- Policy Intake & Quote Screening
- Automated Claims Triage Pipelines
- Document Parsing & CRM Sync
Merchant Cash Advance (MCA)
Direct Funders & ISO Brokerages
High-velocity lead triage engineered to connect with merchants in seconds. Automate inbound qualification, ISO communication pipelines, and bank statement doc intake.

Law & Legal Practices
Personal Injury, Corporate, Family & Immigration
Confidential prospective client intake agents that screen case merits, schedule attorney consultations, and query case precedent and internal knowledge bases.
Engineered Systems
- 24/7 Case Intake & Merit Screening
- Consultation Booking & Calendar Sync
- Secure Document & Precedent RAG
Medical, Ortho & Dental
Private Practices, Clinics & Specialty Care
Front-desk voice AI that handles high-volume appointment bookings, answers FAQs, coordinates patient intake forms, and routes urgent clinical requests.
Engineered Systems
- Voice Patient Appointment Booking
- Pre-Visit Questionnaire Automation
- After-Hours Triage & Scheduling
Home Improvement & Services
Contractors, Roofing, HVAC, Plumbing & Solar
Capture high-ticket inbound jobs before competitors reply. Voice agents book estimate visits, while automated SMS sequences nurture pending quotes to close.
Engineered Systems
- 24/7 Emergency Dispatch Voice AI
- Automated Estimate & Quote Follow-Up
- Field Service CRM Integration
WHY WORK WITH ME ON AI & OPS?
A senior engineering partner focused on business continuity, practical team adoption, and reliable systems.
Business Continuity First
Zero operational downtime for revenue-generating systems. Every AI integration cleanly augments your existing infrastructure with strict backward compatibility.
Practical Team Adoption
Tools your team will actually use. By pairing structured rules with modern language models, new workflows fit into existing habits instead of forcing steep learning curves.
Direct Senior Access
No account managers, junior handoffs, or outsourced code. You work directly with a senior architect who writes the code and understands your infrastructure.
Pragmatic Architecture
I challenge assumptions, test edge cases, and cut unnecessary complexity. If a simple script or webhook solves the problem better than an LLM, that is what we build.

Sergio Gonzalez
AI Systems & Operations Architect • RealtyKPI
Founder of RealtyKPI and senior AI systems architect. I build executive intelligence systems, conversational Voice/SMS/Email agents, custom fine-tuned models, and reliable cloud backends that eliminate operational bottlenecks without disrupting existing workflows.
With deep experience in GoHighLevel (GHL), n8n, Google Workspace APIs, FastAPI Python services, and Docker/Kubernetes on AWS and GCP, I build production systems your team can use from day one.
Core Engineering Commitments
- Zero disruption to live production systems
- Deterministic schemas and verified citations
- Direct 1-on-1 senior engineering access
HOW WE WORK TOGETHER
A clear 3-step process focused on zero downtime, maintainable code, and smooth team adoption.
Operations Audit & Discovery
We review your current tools (Google Workspace, GHL, voice and messaging channels, databases) to identify bottlenecks and keep what already works.
Architecture & System Build
I build the system: Voice and SMS agents, custom model fine-tuning, the CEO Alignment Engine, or containerized FastAPI microservices with strict schema validation.
Deployment & Team Adoption
We deploy the system to production with zero downtime, conduct direct team walkthroughs, and hand over complete architectural documentation.
