About Francisco

Software engineer with +15 years of experience. Specialized in AI applied in production: RAG systems, LLM agents (OpenAI, Claude, LangChain), MLOps, and automation with n8n.

Backend development Python/FastAPI and full-stack SaaS with Next.js, React, TypeScript, and Node.js: REST and GraphQL APIs, microservices, Stripe, idempotent webhooks, and deployment on AWS/Azure with Docker, Kubernetes, Terraform, and CI/CD.

I deliver tested, production-ready code. I have built multi-tenant SaaS, RAG assistants with source citations, data pipelines (web scraping, Apache Kafka), and real-time dashboards.

Technical portfolio: RAG agent, SaaS base with Stripe subscriptions, WebSocket monitor, and npm webhook engine.

Key strengths: AI engineer · Backend Python · RAG/LLMs · Cloud DevOps · Enterprise integrations.

    SOFTWARE PUBLISHING
    May 2026 - May 2026
    Full-stack design and development of "Antuan", a conversational assistant with which diners order from their mobile (voice or text) and the kitchen manages orders in real-time. Complete project, deployed and in production.

    • Table Frontend (HTML/CSS/JS): chat with microphone, real menu with 90+ dishes and prices, local cart, and live order status panel.
    • Kitchen Screen: orders grouped by table, drink/food division, status filters, incremental rendering, waiter/bill alerts, and sound notification.
    • Node.js Backend (Railway): secure proxy to Voiceflow (protected API key, whitelist CORS, rate limiting) and persistent order API with atomic writes that survive restarts.
    • Custom Voice: quantity parser, +100 colloquial aliases, variant detection, and voice product removal.
    • Synchronized client-kitchen states (pending → preparing → ready) with automatic chat notifications.
    • CI/CD: automatic deployment on each push (Netlify + Railway). Technical documentation and professional reporting included.
