High-performance GPU/CUDA on NVIDIA Blackwell (sm_120), across three fronts:
- Number theory & cryptography — Miller-Rabin primality, prime gap searches, Pollard's Kangaroo (ECDLP on secp256k1), and empirical verification of the Beal conjecture.
- Differentiable 3D geometry — techniques from scroll-unrolling (winding coordinates, invertible-by-construction maps), applied and stress-tested outside their origin to find where they hold and where they break.
- Vesuvius Challenge — data augmentations, CUDA acceleration and winding-geometry measurement for the Herculaneum scroll pipeline (awarded, May–Jul 2026 — https://scrollprize.org/winners).
- winding-ruler — Winding evidence for the Vesuvius spiral fit: annotation-value measurement, generator post-mortems, and the first collection-wide winding-pitch atlas (35 Herculaneum scrolls, ~207 µm median pitch).
- constraint-gauge — Calibration benchmark for winding constraint generators in the Vesuvius Challenge: criteria pre-registered and hash-sealed before measurement, generators scored per location against human annotations.
- mr_blackwell — Native Miller-Rabin CUDA kernel for NVIDIA Blackwell. CGBN replacement using Montgomery CIOS and PTX carry chains.
- PSCKangaroo — GPU-accelerated Pollard's Kangaroo for secp256k1 ECDLP. Fork of RCKangaroo with concurrent mode, crash-safe checkpoints, and compact 16-byte DPs.
- verimath — Deterministic, third-party-verifiable number-theory agent (factorization, primality proofs) on the CROO Agent Protocol. Every result ships with a reproducible SHA-256 attestation.
- beal_bigint — GPU search for Beal conjecture counterexamples using the by-C^z parametrization. 20K+ hits validated, 0 counterexamples found.
- winding-coordinates — Differentiable winding/shifted coordinates from 3D scroll-unrolling, with the technique's applicability boundary measured: single vs. nested winding, helix vs. phyllotaxis. Live in-browser visualizer.
- icicle-blackwell-ntt — Empirical characterization of ICICLE NTT on consumer Blackwell (sm_120); profiling-driven, with a prototype for the digit-reversal bottleneck.
- bitcoin-puzzle-research — Documented dead ends and empirically refuted approaches in Bitcoin puzzle research.
Empirical before theoretical. Negative results published with the same rigor as positive ones.
Built in pair programming with Claude (Anthropic) — from CUDA kernels to benchmark audits. Every number, commit and decision verified and made by me.
