NEXUS-FORGE is a proprietary Tier-0 architecture designed for global supply chains operating on enterprise-grade ERP systems (SAP/Oracle). This document is a redacted portfolio version of the Master Blueprint, which eliminates the risk of "Stochastic Deadlock" and API Exhaustion by implementing an Asynchronous Sidecar pattern.
The primary achievement of this architecture is the transformation of unpredictable AI forecasts into a deterministic "Digital Twin" model powered by a Neo4j Knowledge Graph. This enables the prediction of cascading failures and the calculation of a logistical "Blast Radius" with mathematical precision, completely isolating core operational databases from probabilistic AI models.

I designed and developed a secure, production-ready e-commerce backend utilizing a clean layered architecture and RESTful principles. Built to handle complex business logic, this project handles everything from user lifecycle management and strict authentication to secure transaction processing and high-speed data retrieval.
Advanced Security & RBAC: Implemented Spring Security with custom JWT filters, BCrypt password hashing, and granular Role-Based Access Control enforcing 3 distinct tiers (ADMIN, USER, SELLER).
Transaction Atomicity: Built robust transaction management to guarantee atomicity and data consistency across order placement and cancellation workflows.
Database & Caching Optimization: Optimized MySQL schemas via complex JPA relationships (@OneToMany, @ManyToOne) and Hibernate custom queries. Integrated a Redis caching layer that slashed product retrieval latency by 88.87% (from 3.37 s down to 375 ms).
Containerization: Fully containerized the application stack using Docker Compose for seamless, reproducible local and cloud deployments.
