Hi, I'm Kavisara
I'm a Computer Networks student at NSBM Green University and a BIT External undergraduate at the University of Moratuwa. My career direction is cybersecurity analysis and network engineering, supported by practical skills in systems, cloud, and secure full-stack development.
A networking and cybersecurity student building practical technical skills.
My main interest is understanding how networks, systems, and security controls work in real environments. I enjoy working with topics like TCP/IP, subnetting, firewall rules, Linux systems, network monitoring, and secure system design.
I learn best by building and testing. My projects and labs help me connect theory with practice — from pfSense firewall configuration and VoIP setup to full-stack applications with backend APIs, databases, authentication, and real-time communication.
Full-stack development is still an important part of my skill set, but my main career goal is to become a Cybersecurity Analyst and Network Engineer. I want my portfolio to show both software-building ability and a strong networking/security foundation.
Education & Studies
My academic path combines computer networks, cybersecurity, systems, programming, and practical project-based learning.
Computer Networks Studies
NSBM Green University
Sri Lanka
Studying computer networks with a focus on cybersecurity, network security, systems, and practical technical project work.
Bachelor of Information Technology External
University of Moratuwa
Sri Lanka
This ongoing degree began before my NSBM studies and supports my technical foundation in programming, databases, systems, web technologies, and IT fundamentals.
What I'm Building Toward
These are the main areas I am developing for my cybersecurity analyst and network engineering career path.
My Learning Journey
Started BIT External Studies
Began the ongoing BIT External degree at the University of Moratuwa before starting at NSBM, building a foundation in programming, databases, systems, and IT fundamentals.
Built Web Development Foundations
Practiced HTML, CSS, JavaScript, React, and Tailwind CSS through personal and academic projects. This helped me understand how applications are built from the user interface to the backend.
Started Computer Networks Studies at NSBM
Began studying Computer Networks at NSBM Green University, with growing emphasis on networking, cybersecurity, systems, and infrastructure.
Explored Backend and Database Systems
Worked with Java, Spring Boot, MySQL, REST APIs, and academic full-stack project work. This improved my understanding of application structure, backend logic, and database-backed systems.
Focused More on Networking and Security Labs
Started positioning my portfolio around cybersecurity and network engineering through projects such as pfSense firewall labs, FreeBSD and Asterisk VoIP configuration, and network/security-focused documentation.
Improving Portfolio and GitHub Professionally
Currently improving this portfolio and my GitHub presence to better reflect my career direction as an aspiring Cybersecurity Analyst and Network Engineer.
How I Learn & Build
Start with fundamentals
I try to understand the core concept first — whether it is subnetting, firewall rules, API flow, authentication, or database design. A strong foundation makes troubleshooting easier.
Practice in labs and projects
I learn best by setting things up, testing them, breaking them, and fixing them. Practical labs help me understand how real systems behave beyond theory.
Document the process
I want my portfolio and GitHub to show not only finished outputs, but also the thinking behind the work — configuration steps, decisions, issues, and solutions.
Where I'm Headed
My main goal is to become a Cybersecurity Analyst and Network Engineer. I am especially interested in network security, monitoring, firewall configuration, system administration, cloud infrastructure, and defensive cybersecurity.
I also use full-stack development as a supporting skill because many modern security and networking tools depend on dashboards, APIs, databases, automation, and clear user interfaces.
Let's connect about networking, security, or tech opportunities.
I'm open to internship opportunities, project collaboration, technical discussions, and connections related to cybersecurity, network engineering, system administration, cloud, and full-stack development.
