    My website gets data from different APIs and compares the data from the APIs in the frontend for a user, this data is stored in a database before it is displayed in the frontend. However i have noticed that results take a very long time to display in front end as more results are stored in the Database which i usually delete via cronjob. I would like to have the results to be displayed to the user much faster. A scenario for fast display of results that comes to my mind is were results that are ready are displayed before others so as to keep the user engaged. I will also like to work on the filter in the fronted so we have a more user friendly filter

The ideal approach would be to use a prewritten script template that has the main features like a paypal clon. The aplication doesn't need to be exactly as paypal, but the concept overall should be similar and as simple as posible. The main functionallity the app should contain are: -Payment gateway: send and recive payments, internal e-wallet. -Cryptocurrency support: Accept crypto payments, buy/sell cryptocurrency, send and recive cryptocurrency, solana cryptowallet.

    If you are familiar with Tradingview then you will know that we can apply script strategies to our chart. Problem is sometimes these indicators are private, meaning you can still add them to your chart but cannot see the source code of that indicator (Pinescript) written by the author. You can use Chrome Debugger tool to debug the Javascript (see screenshot) and get the Pinescript of public scripts. However, with my limited skill in Javascript I could not do the same for the private ones but I'm pretty sure it is still possible using the same method. If you are experienced in Javascript this should not be too hard for you. Skills: JavaScript, Pine Script If you have DONE THIS TYPE OF WORK BEFORE, PLEASE COMMENT IN YOUR PROPOSAL.
