Agent runtime & memory engineer · 78 merged PRs into agent-infra OSS · MSc AI · Shenzhen, China
I work on the layer under the agent — the harness, the sandbox, the memory, the parts that break in production.
- 🎓 MSc student in AI (2025–2028) — research focus: Agent Memory Systems
- 🔧 Core external contributor to bytedance/deer-flow, a long-horizon SuperAgent harness
- 🛠️ Creator of TechSpar — a memory-driven adaptive interview-coach agent (828+ ⭐, 108 forks)
- 🌱 Open to AI agent / LLM infra internships
78 PRs merged upstream since June 2026 — all of them here.
Most land in bytedance/deer-flow (71), where I work on harness internals: sandbox isolation and secret containment, MCP tool routing and validation, prompt-injection guardrails on every path where untrusted text reaches the model, checkpoint/resume correctness under streaming, long-term memory writeback, and the durable task runtime.
