About Me

Suneth Thiwanka Ubeywarna
🎓 HNDIT · 2023–Present

I'm a Higher National Diploma in Information Technology (HNDIT) undergraduate at SLIATE, Dehiwala, with a strong foundation in both Network Engineering and Software Development. I'm currently focused on routing, switching, VLAN configuration, network troubleshooting, and Cisco technologies — working toward a career as a Network Security Engineer.

Alongside networking, I build full-stack applications with Java, Spring Boot, and modern web technologies, which lets me understand systems from the cable to the code. I pick things up fast, enjoy solving hands-on problems, and work well in multidisciplinary teams.
