I'm Yoha, and I love turning abstract ideas into websites that make people go, “Wow!” when they land on them.

To me, building a website is like brewing a magic potion—mix in a bit of design, add a splash of animation, then pour in some logic.

I'm a visual thinker. When I first joined a startup, I used both my frontend skills and my way of thinking in pictures to help turn the complex, abstract world of quantitative trading into something tangible—designing the flow and then building it into a real product.

Let’s rewind to when I was still a pharmacist. Outside of work, I learned how to code by myself. The first time I build a static webpage, it felt like a personal highlight reel moment.

Back then, I had no idea how tough switching careers would be—but I knew that if I didn’t try, I’d always be stuck wondering, “What if?”
