About

Built for intelligent systems.

I connect applied AI, product engineering, and research practice to build useful automation systems with clear business value.

I am an AI Integration & LLM Engineer at Brain Station 23 with a strong background in Natural Language Processing, Large Language Models, and full-stack development. I graduated with a B.Sc. in Computer Science and Engineering from CUET with a CGPA of 3.79 (with Honors).

My work focuses on building enterprise-grade AI agents, RAG pipelines, and intelligent automation solutions. I am passionate about solving complex problems through AI and have published research at NAACL and LT-EDI workshops.
