AI Security Intern, remote · April 2026–present
AI and Agent Security Evaluation Platform · Core Developer
Substantially extended the early open-source JoySafeter framework, independently rebuilding core functionality and expanding security capabilities. Evolved its agent-chat and individual-tool prototype into a unified evaluation platform for LLMs, agents, RAG, and the MCP ecosystem.
- Long-running task runtime. Reworked the FastAPI and Next.js application and Agent Runtime around an Agent Run → Tool Call → Evidence → Report workflow. Used WebSocket, Durable Worker, and PostgreSQL/Redis for asynchronous execution, reconnection recovery, state tracking, and persistence. Background MCP results write back to the originating run. Reworked run-state transitions and stable IDs to resolve concurrent duplicate consumption and support idempotent recovery and retries.
- MCP security tools. Designed a ToolRegistry extension system integrating Garak, PyRIT, Promptfoo, Semgrep, ModelScan, and LLM Guard, with unified schemas, risk labels, and result writeback. Validated 12 MCP services and 79 security tools with no loading failures, covering 53 backend and 21 frontend tests.
- Evidence and reports. Connected source unpacking, isolated sandboxes, MCP and Skills tools, and report generation. Linked runs, traces, tool events, artifacts, and reports to archive evaluation steps, raw outputs, and detection results with traceable evidence.
- Deployment and delivery. Supported production deployment and designed offline delivery and domestic-platform compatibility plans for customer intranets, covering Target/Judge/Agent model services, CPU/GPU/NPU/DCU hardware, domestic operating systems, network isolation, certificates, persistence, and installation, compatibility, quality, capacity, and recovery acceptance.
JoySafety source audit. Audited JoySafety’s input/output moderation, prompt-injection defenses, multi-turn handling, knowledge-base responses, configurable DAG routing, and asynchronous streaming detection.

LLM AI Infrastructure Intern · June–September 2026
Contributed to TAOctx research and development for long-context agents, working on context compression, long-context inference, and distributed decoding performance on Ascend 910C. The team's work was presented in an open talk at HUAWEI CONNECT 2026, and the project is open source.
- Implemented HSP score-once online compression for long-context inference with Qwen3-235B-A22B W8A8 on Ascend 910C NPUs.
- On all 387 LongBench v2 samples longer than 32K, reduced mean prompt tokens by 87.04% and p50 time to first token by 83.89%, with accuracy improving by 1.03 percentage points.
- Optimized distributed inference using vLLM-Ascend and CANN/ATB 8.5.1, including TP8 + EP8 and A3 Flash Decoding. Increased sustained decoding throughput from 4.71 to 27.99 tokens/s, approximately 5.9×.
- Optimized embeddings, KV caching, and lazy decoding in TAOmem, reducing BEAVER prepare p50 by 31.26%, and added batch-token limits to guard against OOM failures.
