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.

Event-Driven Accounting Platforms: What We Learned Building ComptaAI

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.
