Browser Extension

We are looking for a developer to help create a browser extension.

Have to haves:
> be able to work on the most popular browsers
> it needs to detect user action to trigger events
> a back-end web app/database would also be needed that we can manage for generic and user-specific data
> some other integrations needed however, we can discuss this over a call.

Please submit your proposal for consideration, stating what other information you may need in order to get started on the project. Also reference past projects.
