@matthewlong

AI engineer at Magneton Labs building autonomous agent systems, including AgentHero and a cross-session memory server.

Message

At Magneton Labs, I build production-grade AI agent systems for client companies. I architected AgentHero, a marketplace where Claude- and Codex-powered agents are deployed, supervised, and credit-metered.

I also built ContextFS, an MCP server that gives Claude Code and Codex cross-session recall, with more than 2,300 stored memories and hybrid keyword and semantic search. I designed Agent-OS to model agents as supervised operating-system processes.

At YonedaAI, I built GrokRxiv, a research pipeline that uses parallel Claude agents, Gemini peer review, and Codex verification to draft, review, and publish formally verified papers. I also designed JAPL, a typed functional language with a compiler, 170+ tests, and a 46-page documentation site.

Earlier, I developed software and data platforms across AWS, Azure, and GCP. At TSI, I helped achieve 99.95% uptime by migrating critical applications to AWS, and improved performance by optimizing PostgreSQL queries and adding Redis caching.
