Sarbjit Singh — Backend Development freelancer in Ludhiana

The biggest challenge of the project was finding a technical solution that would enable fast and seamless data transfer from the client’s API (which generates data in the JSON interchange format) to the interface (where the collected data is visualized in multiple forms, diagrams, and charts). As direct communication between the frontend and the API would hinder the system’s real-time updates and user experience, our engineers suggested adding backend functionality to the system. The backend communicates with the client’s API, sends requests to the server, and receives data from the client’s system. On top of that, the solution features a PostgreSQL-based database, which stores pre-aggregated data. The system’s backend structure validates and filters the collected data before transferring it to the frontend. As a result, the database’s performance and user workflow is no longer impeded by time-consuming data migrations. For the frontend part of the solution, we used a combination of the React framework and the Redux library. The backend part is built on the Django REST framework.
