About Me | Sumi Portfolio

Hi, I'm Sumi Yong

I’m a UI/UX Designer based in Kuala Lumpur with a background in graphic design and digital product design. Over the years, I’ve worked on a wide range of digital platforms, designing interfaces for SaaS platforms, e-commerce websites, POS systems, food ordering applications, and internal tools such as HR management systems and iGaming back-office solutions.

My work focuses on transforming complex workflows into clear and intuitive user experiences. I enjoy designing dashboards, administrative systems, and operational platforms where usability, structure, and efficiency are essential.

I’ve collaborated closely with developers and product teams to deliver functional and scalable digital products. One of my key projects involved designing an internal HR management system from the ground up as the sole UI/UX designer, defining user flows, layouts, and interface structures.

I’m passionate about creating clean, practical, and user-focused interfaces that help both users and businesses work more efficient
