Project Summary

Pretius built a custom CRM for T-Mobile Polska that consolidated three legacy systems into a modular, OSGi-based microservice architecture. The system comprises roughly 350 modules, uses a broad technology stack (including Java, Node.js, NGINX, Angular, Oracle and PostgreSQL), and integrates with multiple internal systems. The client reported faster feature delivery and continued the partnership for further CRM development.

Adding new functionality required system shutdowns, causing problematic downtimes
Need to refactor the architecture and build a single, scalable custom CRM

Project Deliverables

Modular microservice-based architecture with approximately 350 modules
