I design and build deterministic execution kernels, Arrow-native data tools, and low-latency runtimes where correctness is proven by construction.

Claims name the code path, fixture, and boundary. No end-to-end latency is implied.
Correctness is not a claim at the end of the page.
It is an invariant carried through every decision, byte, and replay.
