We have some Bluetooth Low Energy sensors and gateway. Sensor readings are sent to AWS IoT Core through the gateway. A backend developer has built a serverless structure on AWS using NodeJS and MongoDB. Now, we are looking for a full stack developer to complete the frontend application using ReactJS.
Tasks will include:
o Create a web portal including the following tabs:
- Home: a summary page to show system status (# of active sensors/gatways) and provide quick access to other tabs.
- Dashboards: user can create custom dashboards and add widget to it. Widgets should be movable, resizable, and linked to a connected sensor to display sensor reading. Widget types include digital readout, analog gage of real time sensor reading, chart of historical or real-time sensor readings.
- Gateways: user can register a gateway, remove a gateway and update firmware (we will provide) on the gateway.
- Sensors: user can scan for sensors near the gateway, select a sensor to connect, see sensor readings and disconnect a sensor (all the control commands and readings are through AWS Amplify PubSub).
- Services: user can define actions based on different events. Under the scope of this project, we only consider 2 events: sensor reading falls out of tolerance defined by user and sensor disconnection, and 2 actions: send email notification and send sms notification (through AWS SNS).
o Modifications of backend application and database structure might be needed during frontend development
o We have frontend design on Figma, you will need to build proper CSS to match design and make web application responsive on mobile devices too
o Website routing
- Good knowledge of AWS services
- Experience with IoT projects a plus
- Serverless structure with NodeJS for Lambda for backend and React for frontend
