AWS Real-time Data Web App Development

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 Requirements: - Good knowledge of AWS services - Experience with IoT projects a plus - Serverless structure with NodeJS for Lambda for backend and React for frontend If you are interested, please create a proposal file to include: - Tools cost (must include) - Total development cost and hours (must include) - Lead time (must include) - Some basic information about yourself 1) Link 3-5 of your best related work samples, a demo account or demo video would be helpful 2) How long have you been working in software development 3) Are you working individually or under a company 4) List your strong skills in software development 5) Rate your English level from 0 to 10 6) Will you be available for weekly online audio/video meeting
