Backend & Systems Architecture | AIVON Technologies
Resilient server-side services and high-throughput data processing
REST / GraphQL / RPC
JWT & RBAC Check
Business Execution
ACID Persistence
Standardized Envelope
Receives typed request payload from frontend or third-party webhooks.
Architecture Overview
Our backend architecture focuses on domain-driven design, transactional data integrity, decoupled asynchronous queues, and strictly typed API endpoints for deterministic enterprise operations.
System Layers & Separation of Concerns
API Gateway & Router
Handles TLS termination, rate limiting, request validation, and JWT authentication before passing to microservices.
Service & Business Layer
Encapsulates core business rules, transactional boundaries, and domain events.
Repository & ORM Layer
Abstracts database persistence with connection pooling and query optimization.
Implementation Approach
- Enforce strict repository patterns to keep business logic decoupled from specific database engines.
- Wrap multi-table mutations inside atomic database transactions to eliminate partial write corruption.
- Use asynchronous worker queues (BullMQ/Redis) for slow operations like sending emails or image compression.
Scalable Backend Foundations
A dependable backend never fails silently. We build deterministic, heavily logged, and transactional server architectures that provide a rock-solid foundation for enterprise applications.
Recommended Stack
Scalability Standards
- Stateless horizontal scaling allows spinning up additional container replicas in seconds.
- Database read replicas and connection pooling (PgBouncer) handle high read concurrency.
Security Benchmarks
- Strict parameter sanitization and parameterized queries eliminate SQL injection vulnerabilities.
- Secrets stored securely in environment variables and rotated via AWS Secrets Manager.
