1) Freshcode Portal toolkit: reducing development costs
Time is the most valuable resource and every client wants to get the soonest result without delay and without sacrificing quality.
SOLUTION: We used Freshcode Portal, our own platform developed to simplify the software development process and reduce overall costs. It provides:
Full automation of key business processes without complex diagrams and enterprise systems
Custom ERP development tailored for each client to gain operational, managerial, and strategic benefits
Emergency filter — breaking news on top of others (amber alert, silver alert, blue alert, weather alert)
We offer clients constrained by tight deadlines to benefit from automated and expedited software development processes via Portal. Freshcode dev team used its ready-made toolkit for this project and got an expected successful result.
2) Issues with alert configuring when a set of alerts run over similar datasets
Some events in the alert's search results had the same keywords and caused multiple alert triggers on the same data at the same time.
SOLUTION: We updated alert configuring to handle duplicate/redundant alerts and eliminate unwanted data duplicates when patterns match.
3) Handling notifications on mobile devices depending on their state: Firebase Cloud Messaging issue

During working on notifications service extension we were faced with several issues.

FCM, Data only (silent notification). Initially, we chose to send silent remote notifications via Firebase Cloud Messaging (FCM). Nothing foretold troubles until we faced the killed app state. Depending on the mobile device states, such notifications are handled differently.

While FCM silent push notifications operate perfectly in Foreground, Background and Quit modes, this method doesn't work when the application is closed forcefully (Killed app). So, the idea to set notifications via FCM background (silent) handler failed.

FCM, Notification-Only (alert notification). Then we decided to make a u-turn and try FCM Notification-Only. But after a short analysis, such an approach in our case turned out to be too cumbersome given the specificity of notifications filter configuration (1 location * 2 languages * 3 notification types).

SOLUTION: Finally, we stopped at OneSignal push notifications service and it became a workable solution due primarily to its Data Tags feature. We were looking for a solution to the problem of filtering and coherently categorizing push messages by Location, App Language, and Turn on/off speсific notification (instead of generating plenty of topics for each Location). OneSignal provides filtering of connected clients before sending notifications and therefore it perfectly suits such a task.
