QRFreeBee
SaaS platform designed to help marketing teams track engagement and measure campaign performance through QR codes and short links. Built as a systems design exercise, the project implements link generation, request handling, rate limiting, and analytics pipelines to capture and process scan events. It focuses on turning interactions into meaningful insights, demonstrating an end-to-end approach to building scalable tracking and reporting systems.
Problem
Marketing teams often lack visibility into how offline QR interactions translate into measurable digital engagement. Existing tools either lack flexibility, detailed analytics, or the ability to scale with high request volumes.
Solution
QRFreeBee addresses this by implementing a system that generates trackable QR codes and short links, captures scan events in real time, applies rate limiting to prevent abuse, and aggregates analytics to provide meaningful insights into campaign performance.
