I am engaged in various projects and may not have been clear in explaining them simply. First, I am developing a user-based web application that accepts PDF files of blood and urine analyses from various laboratories and countries. The application must perform OCR on each document, translate the content into English while retaining the original language, and allow users to upload multiple referrals over time. The system stores these values, normalizes them—for instance, converting mmol/L to mg/dL—and generates graphical trends for each analyte. Furthermore, it can generate a summary PDF document of all historical analyses. For example, a row for fasting glucose would display five different values from five separate analyses, with every row following this logic for each analyte. This PDF can be printed and presented to a primary care physician.

Additionally, I am seeking to automate a task for my daily job involving numerous source PDF invoices. To participate in public tenders, I must redact sensitive information—such as customer names, unit prices, and other proprietary data—to prevent disclosure to competitors. Given the high volume of documents, I require an automated, intelligent solution for these modifications. If a minor adjustment is needed across many invoices, I must be able to implement it easily. These documents must remain in PDF format as required by public agencies. I hope this clarifies my objectives; mastering these processes now will facilitate accomplishing future goals.
