Hi, I am Jhon Renier Tambogon,
Currently pursuing a Bachelor of Science in Information Technology, with interests in technology, art, and design. As a layout artist, I create digital graphics with an emphasis on visual composition and typography. I also develop secure web applications that address real-world problems while exploring other areas of programming to expand my technical skills.
I hold a TESDA National Certificate II in Computer Systems Servicing (CSS), with foundational knowledge of computer hardware, troubleshooting, and basic networking. This background complements my software development skills and broadens my understanding of computing. My goal is to combine creativity and logical thinking to produce effective designs and practical software solutions.
