Claim: run existing pandas code on GPU with zero code changes by swapping in a proxy that routes supported ops to cuDF/CUDA and falls back to pandas when needed. Demo shows big speedups for groupby merge and string ops, a slowdown for count axis=1 due to data movement. Tools: libcudf, importlib import hacks, a notebook profiler that reports GPU vs CPU time. Compatibility notes: 100% pandas API claim with caveats, passes 94% of pandas tests.
