Software engineer with 7+ years building AI infrastructure and production workflows. Founder of PengKernel LLC, where I build agent-watchdog — a runtime loop detector for multi-agent LLM systems — along with custom AI tooling for teams. Interested in the reliability engineering side of AI: the stuff that keeps agent systems from silently failing in production.

Agent-watchdog - Runtime loop detection for LangGraph agents

Multi-agent LLM pipelines fail quietly — agents rephrasing the same argument forever, silent deadlocks, graphs that cycle without an exit. Most tools (LangSmith, AgentOps) show you this after the fact. Agent Watchdog intervenes at runtime, like a circuit breaker — watching message similarity and tool-call patterns to halt stuck LangGraph runs before you burn tokens. Built by PengKernel LLC: npm install agent-watchdog.
