Could you build this?
No High-performance document or data parsing in Rust running at 100x speed requires specialized algorithmic optimizations, memory management, and deep parser construction knowledge.
What it would actually take: The system requires hand-optimized zero-copy lexers and state machines (often using libraries like `nom`, `logos`, or custom SIMD-accelerated parsers) written in Rust. The hard part is achieving extreme throughput while maintaining full spec compliance, handling pathological edge cases, and minimizing CPU cache misses and heap allocations. This requires experienced low-level systems engineers with deep domain expertise in formal grammars and systems optimization.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
