Could you build this?
Partial Writing a basic PDF parser wrapper is easy, but engineering a reliable PDF engine from scratch that extracts and reconstructs complex document layout into structured data requires complex layout analysis and PDF spec handling.
What it would actually take: A real PDF engine requires parsing the low-level PDF specification (cos-level streams, fonts, CMaps, operator streams) and performing geometric layout analysis (reconstructing words, reading order, nested tables, and forms from unordered visual text fragments and vector strokes). The stack typically involves Python bindings to high-performance C/Rust parsers (or pure Python using strict parser state machines) alongside heuristic or ML-based document structure classification. The hard part is handling non-standard, malformed, and proprietary PDF variations while faithfully recovering semantics.
