Nymul Islam Moon

I’m an Applied AI & Backend Engineer from Bangladesh with a strong foundation in problem solving, enterprise backend development, and AI-powered systems. My journey began with competitive programming in C/C++, evolved through building large-scale PHP and Laravel-based ERP, HRM, CRM, and E-commerce platforms, and now focuses on Python-first AI engineering. I currently work on designing backend AI systems using OpenAI models, embeddings, Elasticsearch-based semantic search, and Retrieval-Augmented Generation (RAG) to deliver accurate, business-grounded responses. My core interest lies in building scalable, reliable, and trustworthy AI backends that strictly operate on structured internal data, minimizing hallucinations and irrelevant outputs. I enjoy translating complex business requirements into clean API-driven architectures and continuously deepen my expertise in Python, LLM systems, and modern AI infrastructure.
