👀 Want to see all this experience in action?

Everything below runs live in production on my own VPS under @leonobitech — my startup, where I ship production AI automation for SMB clients in LATAM.

The flagship is a complete agent stack for sales and customer service:

  • 💬 WhatsApp sales agent that qualifies leads
  • 📅 Booking agent that schedules meetings and generates payment links
  • 🧩 All orchestrated through custom MCP servers I built to connect Claude with client infrastructure: Odoo CRM · Qdrant (RAG) · n8n · Docker

About Me

Electronic Engineer with 6+ years in software engineering (web, backend, API systems) and 3+ years deep in AI and LLM-based systems — currently orchestrating agents and pipelines, shipping real workflow automation powered by AI.

I work across the stack — Rust for embedded + backend (ESP32-C3, Axum, Tokio), TypeScript / Next.js for product, and custom MCP servers for the AI layer — bridging hardware, software, and AI end-to-end.

My biggest recent bet: launching Leonobitech, shipping production AI automation for SMB clients in LATAM. Details in the production section above ↑
