I'm Tanzim Hossain Romel, a Software Development Engineer at IQVIA and recent BUET CSE graduate. My research focuses on AI for Software Engineering and LLM Security. I'm currently working on an empirical study of remote code execution vulnerabilities in ML model hosting ecosystems (under review at MSR 2026), analyzing ~45,000 repositories across platforms like Hugging Face and ModelScope. I'm also extending ReAgent++ for detecting aligned backdoors in LLM agents and developing a multi-agent framework for database schema generation (SchemaAgent++) using LangGraph with formal verification. My other research includes Design by Contract for LLM APIs, exploring runtime contract enforcement and automatic remediation strategies.
