Eruo Fredoline
Founder and Chief Executive, Ranked Technologies Limited
Eruo Fredoline is a software developer and technology entrepreneur working on applied artificial intelligence. He is the founder of Ranked Technologies Limited (RC 9522220), the company behind Ranked.ng, along with NGPT, its Nigerian-language models, 9jaBench, a public benchmark for how well AI systems handle Nigerian languages, and 9jatesters, a paid network of Nigerian contributors doing field and data work.
His work concentrates on systems that run on local data and local infrastructure rather than on somebody else's cloud, and on the unglamorous parts of that: entity resolution, provenance, and how you know a record is true.
He writes about AI-native development and data ownership, and works between Nigeria and Turkey.
