Hello, I can integrate secure user authentication into your existing HTML web app, while preserving all current functionality. I’ll refactor the project into a proper server-side architecture, add requested features, and prepare it fully for hosting. The authentication will follow security best practices (hashed passwords, sessions/JWTs, input validation), and the code will be clean and well-documented for future maintenance. Questions: – Do you have a preferred backend stack (Node.js/Express, Django, PHP, etc.) for converting the app to server-side? – Should the authentication include social logins (Google, Facebook) or stick to email/password for now? – Which hosting environment do you plan to use so I can align deployment (cPanel, VPS, AWS, etc.)? I am a TOP Rated Freelancer, and you can check my reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project. Thanks and Best regards, Kamran.

My career in web development spans over 6 years, where I've consistently met my clients' requirements with clean and well-documented code, a fundamental aspect of project management that shouldn't be overlooked.
