Experience
Enterprise AI Copilot and RAG Automation Platform
I led the full architecture and delivery of the solution, building multi-channel conversational AI systems deployed across WhatsApp, web chat, and internal business tools. The platform integrates OpenAI LLMs, LangChain-based orchestration, and vector search over private company data, enabling secure, real-time knowledge retrieval from documents, tickets, CRM records, and operational systems.
I designed autonomous multi-agent pipelines for task routing, data extraction, reporting, and workflow automation, and implemented prompt engineering and memory handling to ensure reliable, auditable, and production-safe AI behavior. The system replaced manual support and reporting processes, reducing human workload by over 60% while significantly improving SLA response times and customer experience.
I also implemented monitoring, cost governance, and security layers to ensure enterprise compliance, scalability, and long-term maintainability.
Dynamic Pricing Optimization for LATAM Car Fleet
Demand Forecasting
I designed the models to capture seasonality, trends, and pricing effects, enabling businesses to optimize inventory levels and pricing decisions. This approach improved forecast reliability and supported data-driven operational and strategic planning.
