Nexa Tracker – ERP Application

Nexa Tracker uses a monolithic client–server architecture where all ERP business logic resides in a single NestJS backend. Multitenancy is enforced at both the data and service layers, ensuring strict isolation between organizations while sharing the same infrastructure. PostgreSQL acts as the primary relational datastore with read replicas for scalability, while Redis provides low-latency access to frequently requested ERP data such as inventory snapshots and sales metrics. Telecloud object storage is used for documents and attachments, reducing database load. The system is fully containerized and orchestrated using Kubernetes, enabling horizontal scaling, rolling updates, self-healing, and high availability. Nginx serves as a reverse proxy and load balancer, distributing traffic across backend pods.
