Public content omits secrets and internal infrastructure details; the 10,000+ TTN data figure is scenario-specific, not an independent benchmark. Demo: https://www.tqcores.com/previews/LoRaWAN.webm
4. Cabañas Las Palmas — Next.js/React/TypeScript hotel-management system with a public landing page and private operation panel for cabins, reservations, passengers, payments, extra services, expenses, occupancy and 12-month result reports.

Uses SQLite/better-sqlite3, Tailwind CSS, PDFKit, ExcelJS, Nodemailer, Leaflet, PM2 and Nginx. The application applies defense-in-depth controls while public content omits secrets, passenger data, internal routes and infrastructure details. Deployment preserves operational data, images and backups across updates. Demo: https://www.tqcores.com/previews/Cabañas.webm
5. Web Prevención de Riesgos — Next.js/React/TypeScript professional platform for an Atacama occupational risk prevention engineer, with a mobile self-service admin panel, Firestore/Firebase Storage, server-side Firebase Admin authorization, content and upload validation, service/sector SEO routes, JSON-LD, sitemap/robots, Vercel deployment and WhatsApp contact. Public content omits secrets, personal/client data and internal operations; it is not an external security audit. Demo: https://www.tqcores.com/previews/WebSole.webm

7. Sistema de Inventarios 3DFAB — Django 5 inventory system with components, locations, atomic stock movements, work-order usage, QR codes, alerts and PDF/Excel/CSV reports. SQLite is the local default; PostgreSQL is supported through DATABASE_URL for production. The reviewed local run declares 37 tests and ends with 7 errors caused by a missing static manifest entry in authentication scenarios plus a None-handling validation error; public content omits secrets, records, files and internal routes. Demo: https://www.tqcores.com/previews/Sistema_de_inventarios.webm
