Front-end & Back-end
AETHRA’s platform architecture is designed for performance, scalability, and ease of iteration, leveraging modern frameworks across both the front and back end.
Front-End (User Interface)
Framework – Vue.js for reactive UI components and scalable SPA design
Styling – Tailwind CSS for utility-first, responsive design with consistent spacing and typography
Testing – Playwright for end-to-end testing, regression coverage, and component isolation
Back-End (Server & API)
AETHRA’s backend is built as a microservices architecture, meaning the system is composed of many small, independent services. Each service is responsible for a specific domain, such as authentication, time tracking and compensation logic.
Key Characteristics
Independent operation – Every service runs on its own. If one service fails, the rest of the system continues running.
Isolated data – Each service maintains its own database, ensuring clear separation and preventing cross-service interference.
Scalable design – Services can be scaled independently, allowing the platform to grow without friction.
Event-Driven Communication
To keep services in sync, the backend uses AWS SNS (Simple Notification Service) and AWS SQS (Simple Queue Service):
SNS broadcasts events whenever something important happens (e.g., a new user signs up or a staffing request is created).
SQS delivers these events to the right services in the correct order, ensuring nothing is lost.
This event-driven design keeps the system loosely coupled: services don’t need to know about each other directly, they simply listen for the events they care about.
Benefits
Reliable – One service crashing doesn’t break the entire platform.
Scalable – New services can be added, or existing ones expanded, without major rewrites.
Efficient – Each service only processes what it needs to, while communication is handled automatically.
CI/CD & DevOps
Infrastructure – Hosted on AWS with containerized deployments
Continuous Integration – Automated builds and testing before deployment
Continuous Delivery – Rolling updates with minimal downtime
Monitoring & Alerts – Real-time performance and error monitoring to ensure uptime
AETHRA’s backend is engineered for continuous availability. Even if individual services fail, the platform as a whole keeps running without disruption. This resilience ensures providers, clients, and workers can always rely on AETHRA to be available when they need it most
