Edwin de Jong

Edwin de Jong is an independent software developer who publishes open-source tools through his GitHub repository at github.com/gedejong, where he maintains a focused catalog of practical utilities. His published product range currently consists of Auto-Rotate, a document-processing utility designed to automatically deskew and turn upright every page of a PDF file. The software addresses a common problem in document digitization workflows, where scanned pages frequently arrive tilted, rotated sideways, or upside down, making them difficult to read, archive, or process further. Auto-Rotate analyzes each page individually, detects the correct orientation, and applies the appropriate rotation and skew correction, producing a clean, consistently aligned document without requiring manual intervention. This type of tool falls within the broader category of document management and PDF processing software, and it is particularly useful in contexts such as bulk scanning operations, digital archiving projects, office automation pipelines, and preparation of documents for optical character recognition, where correct page orientation significantly improves accuracy. Typical users include administrative staff handling large volumes of scanned paperwork, archivists and librarians digitizing collections, and developers integrating document cleanup steps into automated workflows. By offering the utility through GitHub, the publisher makes the source code openly available for inspection, modification, and community contribution, following the conventions of open-source distribution. Although the catalog currently contains a single package, it reflects a specialization in lightweight, task-specific software that solves a well-defined problem efficiently, fitting into larger toolchains where reliable, automated PDF page correction is required.
