Full-stack software engineer with 5+ years building and maintaining production web applications in TypeScript, Node.js and React. I like the hard parts: integrating with systems nobody documented, building the first version from a blank page, and making AI tools work inside real engineering workflows.
- 🏨 Software Engineer at HotelShops (Cancún): enterprise ERP integration, internal platforms and AI developer tooling
- 🤖 I work daily with Claude Code; I built an MCP server and reusable Claude Code skills for my team
- 🛰️ M.Sc. in Food Security (UJAT): my terminal project was an IoT traceability system with LoRa sensors and forecasting
- 🏠 I self-host my side projects on a Raspberry Pi 4 with PM2 and Cloudflare Tunnel
- 🌎 Based in Cancún, Mexico (UTC-5), open to remote roles
📡 Señal: self-hosted RSS reader with AI TL;DRs
Full article inside the app, a 1-2 sentence summary from a local LLM (Ollama) or the Claude API, a "Today" digest ranked by embeddings, semantic search, text-to-speech and a live AI console. NestJS · Prisma/SQLite · React PWA · Jest · GitHub Actions. Runs on a Raspberry Pi within a 512 MB heap.
Orders with modifiers, a live kitchen board synced across tablets, scheduled orders with push reminders, cash-close reports, delivery zones on a map, Bluetooth label printing, and a public menu that sends orders to WhatsApp. A local LLM (Gemma via Ollama) drafts customer messages grounded on the live menu. TypeScript · Express · Prisma · Socket.IO · React PWA. Built with Claude Code, directing and reviewing the agent.
ESP32 LoRa sensor nodes (soil moisture and temperature, air, light, rain) feeding an Express service over serial, live readings over Socket.IO, and a FastAPI + scikit-learn service with 7-day forecasts per sensor. Deployed for cacao producers in Tacotalpa, Tabasco, with nodes about 1 km apart.
