How I Built BidXpert — A Real-Time Auction Platform with FastAPI

Hi, I'm Heet Sanghani, a Python Developer and AI/ML Engineer
from Ahmedabad, Gujarat, India. I currently work at BrainerHub
Solutions building backend systems and AI-powered applications.

In this post, I want to share how I built BidXpert — a
real-time auction platform using FastAPI.

What is BidXpert?

BidXpert is a real-time bidding platform where users can create
auctions, place bids, and get instant updates using WebSockets.

Tech Stack

• Backend: FastAPI + Python
• Database: PostgreSQL
• Real-time: WebSockets
• Auth: JWT Authentication
• Deployment: Docker

What I Learned

Building BidXpert taught me how to handle concurrent WebSocket
connections efficiently in FastAPI and manage real-time state.
