Hi, I'm Herenfor.
Focused on agent runtimes / harnesses, AI backends and cross-platform desktop / mobile app development.
Starting from real session data and experiments on system mechanisms, I find and fix engineering problems in agent runtimes, tool executors and local-first applications.
Featured
All projects→DSH Runtime Tuning
A long-running experiment on the agent runtime: find where time goes in real DeepSeek Harness sessions and what is wasted, then fix it with plugins, each change verified with data.
EPUB Reader
A lightweight EPUB reader for Windows and Android that respects each book's own typography. Built with Tauri 2, React, TypeScript and Rust. Local first.
DSH Sentinel
Looks after DeepSeek Harness from outside the main process. It alerts you when a turn finishes, an approval is needed or the AI asks you a question; starts, stops and restarts DSH from the tray; opens a rescue DSH on crash; optional plugin health check. Succeeds dsh-task-notify, for Windows 11 + WSL2.
Agent task execution runtime
Concurrent execution, timeouts, cancellation and process group cleanup for agent tool calls. A runtime experiment driven by minimal reproduction → root cause → fix → combined fault injection and mutation testing.

Class of 2027 undergraduate, looking for internships and jobs in Agent Runtime / Agent Harness / AI backend. Happy to talk.
