What I'm looking for

I'm looking to build LLM-powered systems for blockchain security, smart contract auditing, or complex question answering, where I can apply prompt engineering, RAG, and security analysis while continuing to grow through practical collaboration.

I've contributed to OneSavie Lab at OneDegree (AIFT), bridging LLM capabilities with blockchain security through an open-source project. I implemented prompt engineering strategies in n8n workflows that detected more than five medium- and high-severity smart contract vulnerabilities with over 70% detection accuracy.

At NCKU's Intelligent Information Retrieval Lab, I helped develop an on-premise, LLM-based multi-turn legal QA system with Galaxy Software Services. I designed a multi-stage workflow that identifies missing query information and asks clarifying questions so responses align with complex legal logic.

I've also analyzed 300+ real-world audit reports to extract attack patterns, spoken at COSCUP's Blockchain Track about LLM-driven smart contract auditing, and led recruiting and alumni programming for the NCKU Consulting Club.
