About Me

I am a student currently pursuing a Cybersecurity Degree and also an ICT Diploma graduate.

I am a developer with real-world experience in building functional and secure systems that optimizes business outcomes and brings real-world impact.

Besides, I have strong foundation in Networking and Cybersecurity by learning from hands-on labs and simulations. I enjoy translating technical concepts into practical, working solutions; not just theory talk.

As a hobby and self-enrichment, I also possess some knowledge in electronics by exploring some small hands-on Arduino projects.
