Product design,
from the first messy sketch
to the shipped screen.

Self-taught product designer mapping unfamiliar territory. Six years in visual design gave me the craft; building and shipping real products taught me the rest. Healthcare tools, consumer apps, and brand systems — usually as the only designer on a small team, end to end.

Synetic

An electronic medical record built for the clinic where I work — designed around a SOAP backbone with specialty modules layered on top. My most current and most systemic work, built with an AI-augmented workflow.

Lilist

A shopping-list-and-expense app for Indonesian households. I shipped V1, watched three friends fail to use it, rebuilt it — then caught myself repeating the same mistake in the redesign and started over again.

I think in systems before I think in screens.

I started in mathematics education, spent six years as a graphic designer, then taught myself product design by building real things. After two years away from work raising my son, I came back to tech — and design is where the analytical and the visual finally met.

Today I co-run Sirkala, a two-person studio, with my husband — he engineers, I design. We ship small, honest products one at a time.
