- RoleChief AI Engineer
- StatusOpen to Work
I'm Zubayer — an AI & Machine Learning Engineer with 4+ years of hands-on experience building production-grade intelligent systems. My work spans natural language processing, computer vision, and generative AI, deployed across healthcare, media, and business automation sectors.
Currently serving as Chief AI Engineer at EVU Inc., a venture-backed startup ecosystem with 250+ members, where I architect advanced NLP models, RAG pipelines, and MLOps infrastructure. Previously, I've delivered AI solutions for USAID's Breakthrough ACTION program and international media organizations.
Beyond engineering, I'm a lifelong learner and open-source contributor. I believe AI should be accessible, multilingual, and purposeful — which is why my work consistently bridges technical innovation with real human impact.
