Below is a you could write or present as a technical demo. Title “Happy Birthday with Akka Typed: A Case Study in Advanced Actor Lifecycle, Clustering, and Event Sourcing” Authors (Your name / team) Abstract Modern distributed systems require resilience, elasticity, and message-driven architectures. This paper presents a birthday greeting system implemented with Akka Typed (v2.8+) . We demonstrate advanced patterns: actor lifecycle supervision, sharded birthday reminders, persistent birthday state, and cluster singleton for yearly scheduler. The result is a highly available, scalable “Happy Birthday” delivery system. 1. Introduction Traditional “happy birthday” apps fail under load or lose wishes on node failure. We use Akka Cluster to partition users by birthdate, Akka Persistence to keep birthday history, and Akka Streams for batch processing of wishes. 2. Advanced Akka Features Used | Feature | Purpose in Birthday App | |---------|--------------------------| | Akka Typed Behaviors | Type-safe birthday messages ( Wish , Reply , ScheduleNext ) | | Supervision & Backoff | Retry failed SMS/email delivery without crashing actor | | Cluster Sharding | Each user’s birthday actor lives on a node determined by userId | | Akka Persistence (Event Sourcing) | Store events: BirthdayWished , DeliveryAttemptFailed | | Cluster Singleton | Single yearly birthday scanner that triggers reminders at midnight | | Akka Streams | Process 1M birthday records daily using Source.queue + Sink.actorRef | 3. System Design [HTTP API] → [ShardRegion] → [UserBirthdayActor (Persistent)] ↓ [DeliveryAdapter] → SMS/Email ↓ [Supervised retries] Key code snippet (Akka Typed):

It sounds like you’re looking for a that combines advanced Akka (likely Akka Typed, Cluster, Persistence, or Streams) with a fun, celebratory twist—perhaps a demo or case study built as a “Happy Birthday” example. akka advance happy birthday latest
