About Me

Hello! I'm Joseph, founder and lead developer at Cosname Technologies. I build web applications, mobile apps, and brand experiences for startups and established teams across Kenya.

My journey started at Kirinyaga University, where I built a foundation in software engineering. Since then I've shipped products for clients in retail, education, fintech, and enterprise operations.

I'm committed to open source, mentoring developers, and exploring tools that solve real business problems with clear design and reliable delivery.
