01 introduction
John Laurence
This portfolio represents my journey as someone who learns by creating.
Most of my knowledge didn't come from simply following tutorials—it came from solving real problems, making mistakes, and improving through each project.
From IT support and troubleshooting to developing an IoT monitoring system, Websites, Scripts, every piece of work here reflects my curiosity, persistence, and willingness to learn technologies outside my comfort zone.

Who I Am
I Love Motorcycles. Aside that, I believe the best way to learn is by building. Throughout my journey, I've explored software development, IT support, automation, IoT, and web technologies through hands-on projects. I also leverage AI as a learning tool to better understand new concepts and improve my skills, combining research, experimentation, and practice to create practical solutions. This portfolio reflects my curiosity, persistence, and commitment to continuous learning.
