AuctionHub - Online Bidding System
Real-time bidding platform with PHP
The Problem
Campus project: build an online auction system where users can list items and others can bid in real-time.
The Solution
Built with PHP and MySQL. Users list items, others bid, highest bidder wins. Added real-time updates so bidders see current prices without refreshing. Nothing fancy, but it works.
What I Learned
First real project with database relationships and concurrent updates. Learned about race conditions the hard way when two people bid at the same time. Also learned: input validation isn't optional—users will try to break things.
Key Achievements
- 1Implemented real-time bidding logic
- 2Handled concurrent updates safely
- 3Built admin panel for item management
- 4Created user authentication system
- 5Learned fundamentals of web security
