PD Batu Hias App is my first real-world project, a desktop application I developed for a client with a budget of $1xx and a one-month deadline, including four sprints for development and revisions, built with React.js for the frontend, SQLite for the backend to keep all data localized to a single computer as per client’s requirement, and Electron.js with Vanilla CSS for the desktop application’s build, handling comprehensive product, customer, and transaction management, along with reporting and an interactive dashboard.
