Custom PDF Certificate Script Developer

Job Description: I need a standalone Windows 11 application that automates the generation of custom PDF certificates based on a template. The program should be user-friendly and require minimal manual work. Requirements: User Authentication: The program must require a password before it can be accessed or executed. User Inputs: Course completion date Course approval number Additional custom text Option to manually enter a single student name OR upload a .csv file for batch processing CSV Upload: If using batch processing, the user will upload a .csv file containing student first and last names. PDF Generation: The program should generate individual certificates for each student using a provided template. File naming format: [login to view URL] PDFs must be encrypted to restrict editing, copying, and modification, while still allowing viewing and printing. The program should generate a .zip file containing all certificates if batch processing is used. Technical Specifications: Must run on Windows 11 as a standalone EXE program (not web-based). Should have a simple graphical user interface (GUI) for entering names manually or uploading a .csv file. The final PDF design must preserve formatting and fonts from the template. To prevent unauthorized modifications, PDFs must be encrypted with editing restrictions (128-bit or 256-bit AES encryption). The program should efficiently process batch files with multiple names or allow single-entry mode for individual certificates. Preferred Skills: Experience developing Windows desktop applications using Python (PyQt/Tkinter), C#, or another Windows-compatible language. Experience with PDF generation and encryption libraries (e.g., FPDF, TCPDF, iText, PyMuPDF, or ReportLab). Knowledge of CSV file handling and batch processing. Ability to design a clean and intuitive GUI for user input. If you have experience with similar projects, please provide samples or references. Looking forward to working with a skilled developer to streamline our certificate generation process! All related working files must be made available so we can modify the program in the future.
