Java/Node.js Developer for System Metrics Tracker -- 3

Im looking for an experienced Java or Node.js developer to create an agent/script for tracking system usage metrics on Windows machines. The agent will capture the following data and store it in an XAMPP SQL database: 1. System Login Time: Record the first login time of the user on a daily basis. 2. Logout Time: Record the logout time of the user. 3. Idle Time: Track and store periods of system inactivity. 4. Metrics and Productivity Time: Calculate and store metrics such as productive time (active usage vs. idle time). Responsibilities: Develop a lightweight and efficient agent using Java or Node.js. Implement methods to track system login/logout and idle time. Calculate productive time metrics based on usage data. Integrate with an XAMPP SQL database for data storage. Ensure data security and performance optimization. Provide detailed documentation for the solution. Requirements: Strong proficiency in Java or Node.js. Experience in system-level programming on Windows. Familiarity with SQL databases (specifically XAMPP setup). Knowledge of tracking system metrics like idle time, login/logout times, etc. Ability to optimize the script for low resource usage. Good understanding of data security and encryption for sensitive information. Deliverables: A working agent/script to track and store required metrics. SQL database schema for storing the captured data. Documentation for installation, usage, and maintenance. If you have experience with similar projects, please apply with your portfolio or examples of past work.
