Full Stack / Web Developer needed for Online Data Portal Development

We are looking for a (team of) full stack web frontend & backend developer to develop a web portal for data file uploading, saving and basic visualization.

Main tasks include:

- Build overall server infrastructure

- Build user management structure (three levels of users required: admin user, full user & limited user)

1) Admin user can add users to the team, purchase and assign subscriptions to other users, upload/download/analyze data file, view analyzed data of all users in the team

2) Full user can upload/download/analyze data file, view analyzed data shared from the file owner

3) Limited user can only view analyzed data shared from the file owner

- Create online database for data management

- Create a login page for user to register account and login

- Create a user dashboard after login

- Three functions are required on dashboard

1) Upload a data file (csv or wav, sample file will be provided) and save it as a record in database (I expect 10000 to 500000 data in each file)

2) View previously uploaded data and select a data record

3) Data visualization with plots for selected data record. Basic plotting features should be implemented (pan, zoom, cursor). Some basic signal processing/calculation will be required (we will provide instruction). The selected language/framework should be powerful enough to handle more advanced computation in the future.

- Create subscription and payment structure for the admin user to purchase and distribute to other users in the team. Subscription options should include 30-day free trial, monthly subscription and yearly subscription.

If you are interested, please create a proposal file to include:

- Tools to be used (server, cloud, front-end language/framework, back-end language/framework, database, etc)

- Briefly explain reason for each selected tool

- Tools cost (e.g. server fee, cloud service fee, etc)

- Total development cost and hours

- Lead time

- Some basic information about yourself

1) Link 3-5 of your best related work samples

2) How long have you been working in software development

3) Are you working individually or under a company

4) Do you have any coding related degree, if so list it

5) List your strong skills in Windows software development

6) Rate your English level from 0 to 10

7) Will you be available for weekly online audio/video meeting

8) Do you have development experience with other platforms
