What I’m Passionate About

Mobile Apps

I improve the things that I can to ensure the quality of the UI, UX, and the overall functionality.

Full-Stack Web

The JavaScript ecosystem is great! I love Node, React, and many other related technologies.


I combine algorithmic thinking with an organised code structure to solve problems efficiently.


With a good understanding of raster and vector, I utilise Affinity and Adobe products in doing digital marketing.

I studied Computer Science at Holy Angel University. Having a degree helps. However, the skills that I have now are mostly self-taught and are from work experience. In my pursuit to never stop learning, I’m constantly improving my skills by taking courses such as Harvard’s CS50 via edX for stronger Computer Science fundamentals, and on Udacity and Udemy mainly for app development.
