Enterprise Platform

Auction Management Platform

Enterprise online vehicle auction platform

Overview

An enterprise online vehicle auction platform where sellers list inventory, approved agents bid, and administrators oversee the process. I contribute to both the web frontend and the backend services.

Problem / Context

Auction software carries requirements that ordinary CRUD applications do not. A bid is a financial commitment, so bid integrity and validation matter as much as the interface around them.
Access is not uniform: sellers, bidding agents and administrators each see a different slice of the platform, and agents must be approved before they can participate at all.
Account security is a first-class concern rather than a login form — the platform needs OTP verification, administrator two-factor authentication and controlled password workflows.

Outcome

The platform supports the auction lifecycle end to end: account security and agent approval, auction visibility, live and proxy bidding with validation, and dashboard metrics for oversight.
Security-sensitive flows — OTP verification, admin two-factor authentication, password workflows and session/device management — are handled as platform concerns rather than per-screen afterthoughts.
