About Me

Ayaan Ehsan Mohammed

I am a Generative AI Architect at Ofinno, leading the development of advanced AI-driven systems that power large-scale research. Since joining in April 2025, I have built scalable Retrieval-Augmented Generation (RAG) pipelines for over 150,000 technical documents.

Previously, I engineered Graph RAG-based AI solutions at The Care Clinic and managed distributed data systems at Eviden USA. I hold a provisional patent in Enhanced Retrieval Augmented Generation and possess deep expertise in merging scalability, interpretability, and user-centric automation.

Current Employment Authorization: STEM OPT EAD valid through July 2027. Will require H-1B sponsorship.
