Full-Stack Engineer · B.S. Computer Science · Addis Ababa University

I am a full-stack Engineer focused on building functional, reliable web systems. Through my coursework and internships, I've had the chance to work on platforms adopted by universities, design a multi-tenant SaaS, and build deployed applications that digitize complex workflows. I enjoy clean architecture, structured data modeling, and building features that solve real-world problems.

I'm always looking to learn, collaborate with experienced engineering teams, and take on new challenges. Download Resume
