I need a lean but robust infrastructure to automate repetitive tasks on the backend of my mobile application. My primary focus right now is data synchronization; data in the application needs to be securely and consistently written to, updated, and retrieved from the server. My technical preferences are clear: • Database: sqlite • Language/Framework: Node.js With this setup, I expect you to: 1. Synchronize local data to the cloud at specified intervals, 2. Resolve conflicts using intelligent logic, 3. Log and report error conditions. It's important to me that the code is readable, enriched with comments, and delivered via Git. Including test scenarios and simple "how-to" documentation is also part of the job. I may consider adding API integration and user management in the future; therefore, a scalable architecture would be a plus. If you are experienced with Node.js and sqlite, you can submit a proposal specifying your questions and previous similar work.
