Step 1: Identify @jit Functions

grep -r "@jit" --include="*.py" .

Step 2: Remove Numba Decorators

# Before
@jit(nopython=True)
def compute(x):
    return x * 2

# After
def compute(x):
    return x * 2

Step 3: Add Pyvorin Compile

import pyvorin

@pyvorin.compile
def compute(x):
    return x * 2

Step 4: Benchmark

Compare Numba JIT vs Pyvorin AOT performance.
