Technical Details


  • Tech Stack: Develop the solution with Java Spring Boot for backend services and Vue.js for the frontend interface. Utilize PostgreSQL for database management unless project-specific needs dictate otherwise.
  • Data Handling and Security: The system must aggregate data from all 20 energy units bi-hourly. This information must be encrypted and stored securely online with a minimum storage duration of 10 years.
  • Data Representation: Provide an interactive interface displaying instant data for each unit and detailed analytics over time. There should be an option for data extraction to various formats for in-depth evaluation.
  • Connectivity and Security: Access to the system should be restricted to Nova Grid's internal network with multi-factor authentication, with the possibility of connection via secured VPN for remote analysis.
  • Codebase and Records: Starting anew, as the prior system's code is inaccessible, this project will involve initial development. Nova Grid's Bitbucket repository will be used for code versioning and collaborative work.
