I love building smart, secure, and practical solutions that solve real-world problems — whether it's developing community websites, creating innovative IoT applications, or designing digital gifts that bring smiles to loved ones.

About Me

Education & Experience

With hands-on experience in IoT, Machine Learning, Web Development, and Cybersecurity, I'm driven by innovation, creativity, and making a real impact through technology.

I hold a Master's degree in Artificial Intelligence from Birmingham City University (2022–2023), where my thesis explored "Identifying and Managing Human Mental Fatigue Using AI." Prior to that, I earned my BSc (Hons) in Computer Security from NSBM Green University (affiliated with Plymouth University, UK), graduating with Second Upper Class Honours (2018–2022).

Professionally, I've gained valuable experience across multiple domains:

  • Currently working as an IoT Hardware Engineer at CompleteCyber, where I help build cutting-edge cybersecurity inspection devices with in-house IDS/IPS and ML capabilities.
  • Volunteering as an Artificial Intelligence Lecturer at Genius Biut Academy, where I enjoy teaching and inspiring the next generation of AI talent.
  • Previously worked as an IoT Developer at Arimac Digital
  • Served as a Research Assistant at the Dialog 5G Research Lab in Sri Lanka.

When I'm not coding or soldering a Raspberry Pi, I'm designing smart tools to support daily life, leading tech initiatives in my community, or diving deeper into electronics and PCB design. I'm also passionate about making tech more accessible — from creating a Python learning platform for kids, to building custom smart devices that help people feel supported, connected, and secure.
