Event-Driven Accounting Platforms: What We Learned Building ComptaAI
Accounting systems must stay consistent under load. Event-driven design with Kafka and DDD helped ComptaAI scale without losing trust in the numbers.

Why events
Finance workflows are streams of facts: invoices posted, payments matched, journals approved. Events make those facts explicit and auditable across services.
Stack that supports trust
ComptaAI combines Angular, Spring Boot, PostgreSQL, Redis, Kafka, Vault, and Keycloak—microservices and hexagonal architecture with DDD so domains stay clear.
Business impact
Unified operations, safer identity, and infrastructure that can grow with transaction volume—without rebuilding the core every year.
