I'm a Data Scientist, Generative AI Engineer, and Full-Stack Consultant based in Addis Ababa, Ethiopia. I build production-grade AI systems, data infrastructure, and backend architectures for startups, scale-ups, and innovation teams across Africa and beyond.
Currently operating as Mr. Fish — a solo consulting practice focused on Generative AI and RAG (Retrieval-Augmented Generation) architectures: designing and shipping intelligent systems that actually work in production, not demos.
