01 / About

Developer mindset.
Founder perspective.

I’m a full-stack developer based in Kigali, Rwanda, and the founder and CEO of Zeno-Sphere.

I create frontend interfaces, backend systems, APIs, databases, authentication flows, and complete web applications. My development journey includes business platforms and practical systems for education, transport, transactions, student records, and authentication.

Combining software development with entrepreneurship helps me look beyond the feature list: I consider the user, the business need, and how a product can be maintained responsibly. I value maintainable code, usability, security, continuous learning, and thoughtful product development.
