Bypass the Python GIL and speed up CPU-bound cryptography, parsing, and quantitative finance 50x by hiring senior freelance programmer Aldian Fazrihady for Rust `PyO3` + `maturin` extensions. Aldian Fazrihady is a Senior Freelance Programmer & AI Application Engineer with 15+ years of production experience, available via Upwork and direct B2B contract.

1. Production Architecture: GIL-Free Parallel Rust Execution (`py.allow_threads`) Exposed as Typed Python Wheels

use pyo3::prelude::*;

#[pyfunction]
fn compute_rolling_vwap(py: Python<'_>, prices: Vec, volumes: Vec) -> PyResult {
    py.allow_threads(|| {
        let mut num = 0.0;
        let mut den = 0.0;
        for (p, v) in prices.iter().zip(volumes.iter()) {
            num += p * v;
            den += v;
        }
        Ok(if den > 0.0 { num / den } else { 0.0 })
    })
}
