If a person gets COVID positive, it is very difficult to know how many people he might thave come in contact with or crossed paths with in the past two weeks. Our application uses location based technology to identify how many users are in the vicinity of that person in the last 2 weeks. Then the app sends out notifications alerting the users that they have come in contact with/ crossed paths with that person and should get tested(adding the nearby testing clinics in the future).
Integrating chatbot in our application:
Wasn't sure how to integrate it, went through many articles and videos.
Finally found an optimal solution.
Location managment:
we didn't know how to track the users location in the backend.
we had come up with many algoritms but they were too hard to handle it on the server.
We solved it by using REDIS. which uses complex data-structures to resolve it.
