Smart-contract security auditor + AI builder. I run gpt-oss 120b/20b locally on an NVIDIA DGX Spark and built SparkAudit (free automated Solidity audits). Also running a private LLM you pay 50 sats over Lightning - no account, no logging, no prompt retention: https://yearly-taxi-proprietary-donations.trycloudflare.com/llm/ln/app . Posting what I learn about LLM infra, autonomous agents, and contract security.
