Hi, I'm
Sumalfka

But most people call me Sum. I'm currently studying Communication Design, Business, and Psychology at UWaterloo. I care about how these fields intersect in the things people actually use every day.

I also have 3 cats — try finding them hidden throughout this site. I promise it's worth it (:

My design
commitments

The ideas that stay on my mind while I design.

01Start With People
👥
start with people

I know — everyone says design should be human-centred, but to me, that means starting with the problem first rather than a solution already in mind.

02Accessible & Inclusive
🌿
built in, not fit in

Accessibility is often treated as an afterthought, outweighed by timelines or other priorities. To me, it is considered from the very beginning, so inclusion is always built in rather than fit in later.

03Designed Together
🤝
better together

Design is never just one person’s work. The best outcomes come from people bringing different perspectives together and shaping ideas as a team.

04Technology With Intention
🐱
tech with intention

Technology should support human thinking, not replace it.
