Challenges & Solutions

Challenge

Rendering dense financial charts without thrashing the React virtual DOM

Solution

Adopted Chart.js via react-chartjs-2, utilizing selective re-rendering and Zustand to decouple chart state from the surrounding UI tree.

Challenge

Providing lightning-fast, typo-tolerant stock symbol search

Solution

Implemented fuzzy string matching algorithms operating on an aggressively cached memory index.

Security Posture

Encrypted Transmission

Secure data handling with session persistence

Verified Authentication

Robust JWT-based registration and login system

Protected Endpoints

Restricted API access for portfolio and watchlists
