What I built

IoT Node Design & Integration

Designed and fabricated IoT nodes to be remotely controlled through the system, with each node communicating its state and receiving control commands from the backend server.

Full-Stack Control Platform

A full-stack web dashboard that powers both the admin and user interfaces; admins can create and manage users and IoT nodes, while users can add their own nodes, monitor real-time device states, and control them through intuitive on/off toggles.
