Project description:
"The current prototype already handles basic front-end logic, but it still lives in a vacuum. I need a single specialist to bridge that gap and let the browser talk to the physical world. Your first mission is to wire up real hardware—think common sensor, actuator, or wearable boards—to the existing web application, prove stable two-way communication, and then add an offline-first layer so the system keeps running even when the cloud is out of reach.

Key points you will be touching:
• Physical setup and provisioning of the chosen IoT boards, gateways, or microcontrollers.
• Implementation of a secure, real-time channel (WebSocket, MQTT, or similar) between device firmware and the web UI.
• Local fallback logic: data stored and queued on-device or on a lightweight edge server, automatic sync once connectivity returns.
• Clean hooks in the web stack so future pages or APIs can call device functions without reinventing wheels.

Deliverables for this initial phase:
1. A working integration demo showing at least one hardware input and one output fully controllable from the browser.
2. Offline workflow documented and tested: run the demo with the network disconnected, capture data locally, then re-connect and watch it sync.
3. Short technical write-up (architecture diagram, libraries used, configuration steps) so another engineer can reproduce the setup.

Everything is negotiable on tooling, yet familiarity with common JavaScript and backend frameworks will speed things up. If you already speak Node.js, React, Python, or similar stacks, the hand-off will be painless." (client-provided description)
