Advanced PDF Processing Library Development

Job ID: 39909098

Budget: $30 – $250 USD

I need a standalone PDF library that my backend services can call to generate, modify, and manage documents end-to-end. The most critical capability is reliable generation of tables and grids, even when the data spans multiple pages; text, images, and non-English characters should flow correctly around those tables.

Beyond creation, the same module must merge and split existing PDFs, add watermarks, set metadata, paginate, and apply password-based restrictions. A clean, well-documented API is essential so the functions can be triggered from other microservices without extra wrappers.

Please build in OCR hooks or integrate a proven OCR engine so scanned pages can be made searchable before any further processing. Where encryption or font files are required, opt for permissive licenses only.

Deliverables
• Source code for the library or module (Python, Java, or C# preferred but I’m open to alternatives)
• Build/installation script and concise developer guide
• Sample scripts that:
– create a multi-page table-heavy PDF,
– merge two PDFs, split one, and add a watermark,
– secure the result with a password
• Unit tests covering every public method

I’ll review performance on large (100+ page) documents, visual fidelity of multilingual text, and memory footprint during intensive merge/split operations before final acceptance.

We will discuss more project in detail after connect.
