Mark Lubin · AI Infrastructure & Agent Systems

Dependable systems for long-running agents.

I build infrastructure for AI agents: runtimes and orchestration, memory and context systems, evaluation, and the backend systems that keep them reliable.

About

I spent ten years at Amazon building distributed systems across payments, Prime Video, and AWS Marketplace. From January 2025 through March 2026, I focused on independent research and open-source engineering for persistent agent systems. That work produced Synix, LENS, and CDR. I now work as a Staff Software Engineer at Kinelo, building shared infrastructure for agent runtimes, sessions, events, and operations.
