Developed a web-based job tracking system for a waterproofing business, allowing clients to monitor project progress through a secure web portal accessed via unique QR codes. The waterproofing business needed a way for their clients to track the status of ongoing projects without constant phone calls or emails. They wanted something simple, accessible, and secure. Built a full-stack web application where each job gets a unique QR code. Clients scan the code and are taken to a secure portal showing real-time progress updates on their project. The back end handles job management, status updates, and client authentication. Key features include QR code generation linked to individual jobs, a secure client portal for real-time project tracking, an admin dashboard for managing jobs and updating statuses, and a web-based interface accessible from any device. Python for back end logic, SQL for data management, and web technologies for the client-facing portal.
