Deploy Native Android & Backend Node Js

I have a native Android app and a Node.js-based web admin panel that are ready on my side but not yet live. I need someone who can:

• set up the Node.js environment on my VPS (including environment variables, SSL, reverse proxy and any required services)
• build, sign and publish the Android app (or at least deliver a production-ready APK/AAB)
• connect the app to the web admin’s REST endpoints and verify that all calls—login, data sync, push notifications, etc.—work end-to-end
• handle any minor code tweaks or configuration needed so both layers talk to the same database and file storage
• provide a short hand-off document covering server paths, build commands and where to update future environment keys

Everything is already coded; I mainly need a clean deployment, configuration and test cycle so the system is production-ready. If you are comfortable jumping between Android Studio, Gradle, Node.js, Express, npm and basic DevOps on a Linux server, this should be a concise project.
