About
I progressed from Linux/Windows system administrator to DevOps/Senior Sysadmin, owning infrastructure and deployment for 500+ hosts, NDA-critical environments, and internal HR/InfoSec products.
Today I focus on AI infrastructure, protocol-level reliability and open-source: security fixes, consensus bugs, semantic cache and error propagation in ethereum/go-ethereum, gonka-ai/gonka and gonkalabs/opengnk.
