Full-Stack Feature Integration Sprint

I have an existing Android app that talks to a Node.js backend and a set of supporting Python scripts. I now need to roll out several new features, so the goal of this engagement is purely about adding new functionality from end to end rather than cosmetic tweaks or bug fixes.

You will take the feature specs we discuss, update the API layer in Node.js, reflect those changes inside the Android client (Java/Kotlin), and, where required, expand the Python utilities that handle background processing and scheduled tasks. Clean, well-commented code committed through Git and a short README covering setup or migration steps are essential.

Deliverables
• Updated Node.js endpoints and middleware
• Android UI & logic that consumes the new endpoints
• Extended Python modules, each with a quick unit test
• Post-deployment sanity checklist confirming the new functionality works across all layers

Please be comfortable working across all three parts of the stack; I’m ready to share repo access and detailed wireframes as soon as we kick off.
