Software Developer • AI Engineer • SaaS Builder

I’m a Junior Software Developer at Energy One and a postgraduate student at the University of Warwick, currently studying MSc Applied Artificial Intelligence. I previously graduated with a First-Class BSc in Computer Science with AI from Coventry University.

I build AI-powered systems, automation tools, and SaaS products — combining machine learning, backend engineering, and cloud infrastructure to turn real-world problems into clean technical solutions.
