Samuel Wanyua

Breaking barriers with
Accessible innovation.

I am an AI Engineer & Software Developer building accessible, human-centered technology. I specialize in speech recognition, NLP, and machine learning — with a focus on making AI work for underserved communities. I bridge the gap between research and real-world deployment — from fine-tuning models to shipping production-ready products.

Currently building Chacha Speech — a speech therapy companion for children with communication disabilities, and developing bilingual ASR systems for Kenyan English and Swahili. Winner, HackAbility 2026.
