Software. Bitcoin. Security. Combat.
Currently building BJJChat, TellForever, Aircraft Spa,
Nostr-Q, devday, linear-scout, VoxOps, ericgrill.com
Training for Competition prep, next tournament TBD
Three Systems • Lab • MCP Servers • Bitcoin • Claude Code & AI • Dev Tools • Projects • Writing
I build systems for people who refuse to be owned.
Software, Bitcoin, Security, Automation
Infrastructure that moves real value. Systems that survive when others fail.
BJJ, Competition, Discipline
IBJJF champion. Training daily. The mats teach what theory cannot.
Blog, Research, Field Notes
Live experiments. Not tutorials. Dispatches from the edge.
Enter the lab. Each experiment is live and built to be explored.
