About Me

I am a Medical Doctor and AI Expert with a passion for merging the worlds of healthcare and artificial intelligence. With a robust 5-year track record, I have delivered innovative AI solutions across various domains, including audio processing, computer vision, and natural language processing.

As the lead Engineer and Researcher behind SabiYarn, Nigeria's first LLM capable of text generation in multiple Nigerian languages, and the co-founder of Autobiz, a platform for business automation (SMEs), I am committed to pushing the boundaries of AI for meaningful societal impact.

Currently, I am pursuing a Master's degree in Robotics and Autonomous Systems with a focus on biomedical engineering at Arizona State University, further expanding my expertise at the intersection of healthcare and cutting-edge technology.

My unique blend of clinical expertise and technical proficiency allows me to identify healthcare challenges and develop innovative technological solutions. I am particularly interested in the integration of AI, robotics, and nanotechnology to transform healthcare delivery globally.
