About

I'm an Informatics and Computer Science graduate from Strathmore University (2026). I build full-stack web and mobile applications, backend services and automations, and I prototype AI features with LLMs and machine learning. I bring a solid foundation in databases, system design and secure infrastructure, and I care about clean, maintainable, well-documented code. I'm currently growing my skills in Full Stack Development, AI Engineering, Machine Learning and DevOps.
