I architect complete IoT systems from embedded firmware to React dashboards, bridging hardware and software with scalable, production-ready solutions.
Visualizing the complete pipeline from physical sensor acquisition to user interface rendering.
RFID-based vehicle access and parking management system with real-time monitoring, MQTT communication and Firebase logging. This system automates entry/exit protocols and provides a live dashboard for facility managers.
Developed ESP32 firmware for RC522 RFID authentication, implemented MQTT communication, built Node.js middleware for access logic, and created React/Firebase dashboard for real-time parking management.
Every bin is equipped with an ultrasonic sensor for fill-level detection, an IR sensor for automatic lid control, and an ESP32 for real-time data transmission. When the bin reaches around 85% capacity, the system sends an alert to the server so authorities can schedule collection efficiently.
Eliminates manual attendance by using BLE advertising from smart ID tags/mobile phones and ESP32 receiver nodes placed in classrooms. Presence data is transmitted via MQTT → Node.js → Firebase and displayed on a real-time dashboard without any student interaction.
