I am a UX/UI designer and founder of Opacity, a design studio based in Singapore.

Before establishing Opacity, I spent seven years as a designer and developer at Hitachi Asia where I led the company's overall web presence in 6 Southeast Asia regions. Prior to that, I was a web designer at Comwerks before it acquired by Wunderman in 2010.

This is a personal site to showcase my works during my tenure at the past organisations.

What do I do, anyway?

In a nutshell, I design products that work.

It's true that when users first encounter your product, they will size it up first for its aesthetic. However, a product that works goes beyond looking pretty. It does its job — achieving both the users and business goals. You've heard before: design is a problem-solving activity.

Have you ever visited a website or an app and only to feel it’s going to be impossible to find what you want? A poorly designed product does make users frustrated.

Lack of clarity, bad navigation, or simply slow loading may cost your business as your users leave the product without taking any desired action.

A successful design solves problems. It leads the users to find exactly what they are looking for. It directs them to purchase a product, fill out a contact form, or call your sales phone number.

Thus, it will increase your revenue without a need to increase your advertising spend.

That's what I do.
