Seeking Guidance on Integrating Advanced Features into Coaching App

Hi, We are a Upsc coaching institute in India. We are looking to develop an app to help students grasp current affairs that are relevant to UPSC. We want that app to not only deliver current affairs from our website, but also fetch important information from various top news sites in India filtered by keywords. We have talked to various local app developers (both agencies and freelancers), but could not find someone who can confidently add this functionality to the app.

One more functionally that we want in our app is “Filter current affairs by date” just like on our current affairs page ( https://compass.rauias.com/current-affairs-upsc/ ). This feature helps students go through current news by date helping them keep track.

So, if anyone has done it in past, we would love to discuss how it can be done or anyone having the code to integrate these features?

Looking for solution ASAP.
