I identify security and protocol

I identify security and protocol gaps in major open-source infrastructure and ship fixes upstream. Contribution to Coinbase's x402 micropayment protocol (merged PR): added a security API built with TypeScript. Contribution to OQTOPUS quantum ecosystem (PR #79): built a zero-dependency Python attestation module using standard-library SHA-256 cryptography that detects tampered quantum hardware jobs.
