AI / LLM Engineer — agentic systems, RAG, and the evaluation infrastructure that keeps them honest.
I build LLM systems with the same operational discipline as backend software — agentic workflows, retrieval over FAISS and pgvector, and evaluation harnesses with blinded judges so a change can be measured rather than argued about. Software Engineering graduate of Universiti Teknologi Malaysia (July 2026, First Class), currently Agentic AI Engineer at BLOOMTECH, Inc. and ERP Developer at Hirdaramani Bangladesh. Certified AMD ROCm Associate. Previously shipped production software for clients in the US, Luxembourg, Bangladesh and Malaysia.
