HULM Solutions Business Suite

HULM Business Suite is an enterprise SaaS platform built for businesses in the FMCG and Telecom sectors. It’s based on a modular microservices architecture, consisting of both Core API and Application layers. I developed domain-driven REST services for modules like catalog, inventory, customer, promotions, reporting, and invoicing. The system also integrates taxation features compliant with ZATCA (Saudi Arabia) and FBR (Pakistan), supporting automated e-invoicing, VAT calculation, and real-time tax submissions. The suite was designed with scalability and maintainability in mind, featuring secure identity management through Keycloak and a robust backend structure that ensures smooth inter-service communication and high performance across multiple business applications.
