Backend Development - FastAPI API Implementation

Backend Development – Nagara AI Smart City Platform

Assigned Module

Backend Architecture & API Development

Objective

Design and develop the backend architecture that powers communication between the frontend, AI services, databases, and external map services. The backend will serve as the central layer responsible for API management, request processing, authentication, business logic, and data flow across all platform modules.

Responsibilities

Backend Architecture

• Design scalable and modular backend structure
• Implement service-oriented architecture
• Manage data flow between frontend and backend services
• Ensure maintainability and extensibility of APIs

API Development

• Create RESTful APIs using FastAPI
• Implement request validation and response serialization
• Handle error management and exception handling
• Maintain API documentation using Swagger/OpenAPI

Authentication & Security

• User authentication APIs
• Authorization and role-based access control
• Secure API endpoints
• Session and token management

Core Service APIs
