I will build a node js backend with secure login and database for your app
Stefano
About this gig
AI builders create a nice interface quickly, but the backend is where most apps break: logins that do not work, data visible to the wrong users, keys exposed in the browser.
I am a senior full-stack developer with 9+ years of experience building backends, databases and authentication systems (OAuth2, JWT, two-factor authentication) for production applications.
What I can do for you:
- Build a Node.js REST API for your app
- Set up secure login and sign-up
- Design your database (MySQL or MongoDB)
- Make sure each user only sees their own data
- Move exposed keys and secrets to the server side
- Review an existing Node.js backend and fix the issues I find
You receive a short written summary of what was built and why.
Please note: this is a practical development and review service, not a certified penetration test.
Message me before ordering so I can look at your project first.
Parlo italiano: puoi scrivermi in italiano.

Senior full-stack developer with 9+ years of experience building and running web apps in production. I work with Node.js, JavaScript, React and Angular, with MySQL, SQL Server and MongoDB, and with Linux, Docker, Nginx and AWS.
I help founders and small teams who built an app with AI tools and need a developer to finish the job: fix the bugs, build a backend with secure login, and put the app online on their own server and domain.
Clear communication and honest estimates: I tell you before you order if something is not a fit. Parlo italiano.
FAQ
Is this a penetration test or a security certification?
No. It is a developer service focused on building the backend correctly and fixing the most common problems: access rules, authentication and exposed secrets.
Will my existing data be safe?
I ask you to make a backup before I start, and I test changes before applying them to live data.
My app needs more than 5 database tables. Can you still help?
Yes. Message me with the details and I will send you a custom offer.
Can you also add payments to my app?
Contact me first with the details and I will tell you if it fits your project.
