Overall Information

Internship flow & timeline

My internship took place in Jal El Dib (Abou Jaoude building 22, 1st floor, Matn – Lebanon), from 20 July to 20 September. It followed a structured technical path from IoT foundations to practical web development.

  • Introduction to Joya Smart: company overview and main working sectors (IoT, automation, field integration).
  • Networking recap: IP fundamentals, routing & switching concepts, and essential networking building blocks.
  • IoT protocols: M-Bus, Modbus, MQTT, LoRa and where each protocol fits in real systems.
  • Web development (main part): PHP, JavaScript, jQuery, Bootstrap, HTML/CSS, and MySQL recap (structured DB + relations).
  • Mini projects: reservation system and university enrollment system to practice end-to-end integration.
  • Sensors & criteria: what to evaluate before installing a sensor (conditions, selection criteria, and correct sensor type).
