Undergraduate student in Software Engineering at Southwest University, Chongqing. I work on AI agents — recently action reuse for GUI agents and context minimization for private RAG. Beyond research, I do full-stack engineering and enjoy taking systems all the way from prototype to deployment and operations.
Research
GUIzam: Selective Pixel-Level Action Reuse for GUI Agents.
First author, under submission to AAAI 2027. A Memory-First cascade that separates
action proposal from execution permission: guarded exact reuse, candidate re-grounding,
an execution-permission gate, VLM fallback, and write-back only after verification —
substantially reducing erroneous memory executions and inference cost while
preserving task success.
QCD-RAG: Policy-Preserving Query-Conditioned Context Minimization for Private RAG.
First author, under submission to AAAI 2027. Formalizes the problem of
post-authorization generator exposure for private RAG over access-controlled corpora.
A four-stage filter renders evidence according to policy clearance and scores each
unit by answer support, sharply reducing identifier exposure and prompt length
at comparable answer quality.
Projects
NaiveBass (2026 — present) — A local-first AI knowledge-base desktop app. Development is driven by a Python evaluation framework as the sole judge; the product core is TypeScript, with Tauri / Rust providing controlled file writes and Git auditing.
"H" Rebate Points Platform (2026) — Outsourced delivery covering accounting, rebates, withdrawals and settlement. Solely responsible for the backend and for deployment and operations across two servers; the money path is guarded by transactions, row locks, distributed locks and idempotency keys. Completed a zero-downtime migration of legacy data.
RISE · Lingzhi Yuxue (2025) — An immersive AI education system combining RAG, MCP and digital humans, serving students, teachers and administrators. Designed and developed the frontend and integrated the backend through launch. Demo paper at WWW ’26 (fourth author); Grand Prize in the “Challenge Cup” open competition track.
VirTour (2025) — An immersive virtual-tour system where a digital human guide strings together panoramic views and sight commentary. Built the frontend adaptation and core features. National Second Prize, China Collegiate Computing Design Competition.
Misc
Currently participating in Tencent’s Open Source Summer program.
Small things I’ve built: SudokuWithLLM, an MCP-based web Sudoku; 106Controller, a Socket-based remote-control iOS app.
Based in Chongqing. Looking for internships in AI agents / LLM applications, in Shanghai, Shenzhen, Guangzhou or Chongqing. This site is static HTML, served by Caddy.
