Hello, Building the backend for your location-based social platform requires a scalable and efficient approach to API development, real-time communication, and secure authentication. I can implement robust server-side functionality that integrates smoothly with your React frontend while optimizing performance and security. I have a few questions on it: Do you have a preference for the database system (PostgreSQL, MongoDB, etc.), or should I suggest the best fit? Should the WebSocket chat feature support group conversations or only one-on-one messaging? How frequently should the HERE API data be cached to optimize request limits? I’d be grateful for the opportunity to contribute and would be honored to be considered for this role. You can check my reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project.
