Junha Park

Hi, I’m Junha.

I work on evaluations for LLM agents, with a particular interest in autonomous open-source maintenance and long-horizon software engineering.

I authored a task for Terminal-Bench and am building a RISC-V VM benchmark to study how agents’ architectural decisions depend on the maturity of their starting codebase.

I created FastRoll, a Rust client for the JAM protocol, which received the JAM Prize Milestone 1 award. I’m also a Rank 3 Fellow in the Polkadot Technical Fellowship and a member of the Gray Paper editorial board.
