About Me

My Journey

I have always enjoyed identifying problems in my life and finding solutions for them. When my parents started a group buying business, much of the work was done manually. After searching for pre-made solutions online and finding none that fit our business model, I decided to create my own. This marked the beginning of my journey as a self-taught developer.

I began learning web development, and it immediately clicked with me. Hours would pass by as I immersed myself in learning and coding. In a short time, I built both a marketplace and an internal tool to manage it, providing a customized solution for our business needs.

My Hobbies

stenography keyboard

I’m interested in stenography, a method that allows for faster typing by pressing multiple keys simultaneously. Additionally, I designed a custom split keyboard PCB to ensure the key layouts are ergonomically suited to my hands.
