Upgrade VaultX Full-Stack Platform -- 2

VaultX is already live in Python 3 / Flask with a Bootstrap-based front end and a SQLite data layer (MySQL optional). It works, but it doesn’t feel finished. I want to transform it into a polished, production-ready “Digital Memory Locker” that delights users and scales cleanly... (Budget: ₹12500 - ₹37500 INR, Jobs: Bootstrap, Flask, Frontend Development, Git, JavaScript, PHP, Python, SQLite)
