PORTFOLIO NEXUS

Abstract

Portfolio Nexus is an advanced AI-powered wealth
management and investment optimization platform
designed to address the growing challenges of
privacy, asset fragmentation, and inefficient
financial tracking in the modern fintech ecosystem.
Existing investment platforms often require
intrusive permissions such as bank account linking
or email access, thereby compromising user
privacy and data sovereignty. To overcome these
limitations, the proposed system introduces a
“Zero-Dependency” architecture that enables users
to manage and monitor their complete financial
portfolio without exposing sensitive credentials.
The platform integrates multiple asset classes
including stocks, mutual funds, cryptocurrencies,
gold, fixed deposits, and real estate into a unified
dashboard that provides a comprehensive view of
personal wealth. The system employs a
Microservices Architecture using Java Spring Boot
for secure backend services, Python FastAPI for
market analysis and AI orchestration, React.js with
TypeScript for an interactive frontend, and MySQL
for reliable data persistence. Real-time market
valuation is achieved through integration with
public financial APIs, ensuring accurate portfolio
updates without manual intervention. A major
innovation of the system is the integration of a
Generative AI advisory engine that utilizes Large
Language Models to provide personalized
investment guidance, portfolio health analysis, tax
optimization strategies, and affordability insights
through natural language interaction. The proposed
platform improves automation, scalability, security,
and user engagement while preserving complete
control of financial data. Thus, Portfolio Nexus
combines intelligent analytics, privacy-first design,
and AI-driven financial mentorship into a modern,
scalable, and user-centric wealth management
ecosystem.
