Bulk Push Notification Scheduler
Muhammad Anees
The scheduler behind bulk push campaigns at DPL, sending to Android (FCM) and Huawei devices.
What I did
Built the bulk push scheduler on .NET
Read recipients in chunks instead of loading the whole list
Sent with controlled parallelism using a semaphore
Result
700–800k notifications per run, delivered in 7–8 minutes
