Project description
NexaCore ERP consolidates accounting, inventory, HR, and reporting into a unified platform to eliminate data silos and give executives real-time operational visibility across departments.
Challenges we tackled and how we handled them
Cross-Module Data Consistency - Adopted event sourcing so modules publish and subscribe to business events; downstream modules maintain eventually consistent, replayable views.
Complex Role-Based Access - Implemented RBAC with role inheritance and ABAC rules for fine-grained permissions, allowing admins to compose roles across modules safely.
Report Generation at Scale - Provisioned a separate OLAP reporting database with real-time replication and pre-computed aggregations for heavy executive reports that don’t affect transactional performance.
Multi-Currency and Localization - Added a currency conversion service (real-time rates) and configurable tax rules for jurisdiction-specific reporting.

Problem Solving
Challenges We Tackled
Every project presents unique challenges. Here's how we approached and solved the key technical hurdles.
Cross-Module Data Consistency
Changes in one module (like inventory) must instantly reflect in others (like accounting) without data discrepancies.
Implemented event sourcing pattern where all state changes are captured as events. Downstream modules subscribe to relevant events and maintain eventually consistent views.
Complex Role-Based Access
Different departments need different access levels, and some users require cross-functional permissions.
Built a flexible RBAC system with role inheritance and attribute-based access control (ABAC) for fine-grained permissions. Admins can create custom roles combining permissions from multiple modules.
Report Generation at Scale
Executive reports need to aggregate data across millions of transactions without impacting operational performance.
Separate OLAP database for reporting with real-time data replication. Pre-computed aggregations for common reports with on-demand drill-down capabilities.
Multi-Currency and Localization
Global enterprises operate in multiple currencies and regulatory environments.
Currency conversion service with real-time exchange rates. Configurable tax rules and reporting formats for different jurisdictions.
