✈️ Airline Ticketing System (FastAPI Microservices)

🧩 Overview

This project is a microservices-based Airline Ticketing System built using FastAPI (v0.115.0) and PostgreSQL. It’s part of my personal learning journey — transitioning from .NET 6 background to mastering Python backend development.

Each service is designed to be independent, lightweight, and RESTful, with interactive API documentation powered by Swagger UI.

⚙️ Tech Stack

Framework	FastAPI (v0.115.0)
Language	Python 3
Database	PostgreSQL
API Docs	Swagger UI (auto-generated by FastAPI)
Architecture	Microservices

🧱 Services

🧑‍💼 User Service

Manages user registration, login, and authentication
Status: ✅ Completed

🛫 Flight Service

Handles flight schedules, routes, and airline data
Status: 🚧 In Progress

📘 Booking Service

Manages ticket booking, payments, and seat availability
Status: 🚧 In Progress

Each service runs on a different port and communicates via REST APIs. Eventually, these services will be containerized and connected using Docker Compose.

🚀 How to Run (Development Mode)

1️⃣ Clone the Repository git clone https://github.com//airline-ticketing-system.git cd airline-ticketing-system

2️⃣ Setup Virtual Environment python -m venv .venv source .venv/bin/activate # for Linux/Mac .venv\Scripts\activate # for Windows

3️⃣ Install Dependencies (per service) cd user-service pip install -r requirements.txt

4️⃣ Run the Service uvicorn app.main:app --reload --port 8001

Then open your browser:

💬 About This Project

This is a self-learning project — I’m exploring how modern backend systems are built in Python. While I’m still learning, I focus on clean code, readable structure, and production-oriented architecture.

🧡 My goal: to grow as a software engineer who can adapt across tech stacks and still write maintainable, scalable systems.
