Case study
Reliable multi-channel notifications at scale.
VectaSinq is a Java-focused notification platform with services for templates, delivery, analytics, and channel orchestration. It is designed to make asynchronous delivery both dependable and observable.
Architecture
Asynchronous delivery with clear failure handling.
- Spring Boot services coordinate templates, delivery, analytics, and channel orchestration.
- Firebase push, email, SMS, Slack, WhatsApp, and webhooks allow delivery through the channel each audience uses.
- Kafka handles asynchronous events while Redis supports hot-path state and PostgreSQL stores durable application data.
- Retry strategies, rate limiting, dead-letter handling, and analytics are built into the delivery model to support reliable throughput.
- Prometheus provides latency and throughput visibility for the operations layer.
Delivery
Automated cloud delivery for the notification workload.
The platform is delivered with GitHub Actions, Terraform, Docker, and Kubernetes on AWS EKS, ECR, RDS, Secrets Manager, and Load Balancer.
