Your job is end-to-end: keep what is already online stable, design and ship new user profile pages whenever I request them, and adjust the database architecture so each new feature fits smoothly into production.

You’re free to suggest the best stack for the job; I’m open to modern frameworks such as React, Vue, Angular or a classic server-rendered approach if it suits the project better. What matters most is that the authentication layer is bulletproof, follows current OWASP recommendations, and can plug into future modules without rewrites.
