PrintMe: Interactive Invoice Designer App

I'm looking for a skilled C# and WPF developer to create a Windows application, PrintMe. This app should utilize the MVVM architecture and enable users to design and manage invoice templates with ease. The software needs to feature a sleek, modern user interface powered by WPF Fluent UI. Project Overview: “PrintMe” is a dynamic and user-friendly Windows application built using C# and WPF in the MVVM architecture. The application enables users to design, customize, and manage invoice templates seamlessly. It features a modern and professional user interface, leveraging WPF Fluent UI for an enhanced look and feel. Additionally, the software will include a secure installation process with a serial key to prevent unauthorized access or cracking. Key Features: 1. Drag-and-Drop Designer • Users can drag and drop design elements (e.g., text boxes, images, tables) to create invoice layouts. • Snap-to-grid functionality for precise alignment of elements. 2. Database Integration • Connect to various databases using ODBC. • Drag and drop database fields onto the design canvas to bind data dynamically. 3. Template Management • Save designed invoices as reusable templates. • Load and modify templates as needed. • Template can map with the one printer or muitple printers with diffrent page size, when we click print should print selected printers. 4. Print and Export Options • Print invoices directly from the application. • Export invoices in binary format or any format which our PrintMe application will accept. 5. Modern UI Design • Use WPF Fluent UI for an attractive and intuitive user interface. • Provide customizable themes to suit user preferences. 6. Secure Software Setup • Implement a serial key-based activation system to prevent unauthorized access or software cracking. • Ensure robust encryption and validation for serial keys. 7. MVVM Architecture • Ensure separation of concerns for maintainable and scalable code. 8. Implement version control for invoice templates to allow users to revert to previous versions if needed. Deliverables: • Fully functional WPF MVVM application with all the above features. • Source code with proper documentation.  • User guide for setting up and using the application, including activation steps. Technical Stack: • Programming Language: C# • Framework: .NET Framework 4.8 • UI Framework: WPF with Fluent UI • Database: ODBC-compatible databases • Licensing/Protection: Secure activation system (e.g., License Manager or custom implementation with encryption) Project Milestones: 1. Initial UI Mockup and Approval. 2. Development of Drag-and-Drop Designer. 3. Integration with ODBC for Database Field Binding. 4. Implementation of Template Saving and Printing Features. 5. Development of Serial Key Activation System. 6. Final Testing and Delivery. Requirements for the Freelancer: • Proven experience in C#, WPF, and MVVM architecture. • Familiarity with Fluent UI or similar modern UI frameworks. • Knowledge of ODBC integration and database handling. • Expertise in software licensing and security measures to implement an uncrackable serial key system. • Strong portfolio demonstrating similar projects. Please note, the specifics of the invoice template customizations are yet to be determined. Therefore, flexibility and a capacity for iterative development will be key.
