I design the unglamorous software that keeps trains, clinics and invoices running.

In a hurry? and every case study folds down to its gist.

You’re skimming: every case shows its outcome and key sentences. for the full stories.

Case studies

Each one opens as a full story, or as a one-minute gist.

About

Jun Park standing at a whiteboard covered in sticky notes and sketches, leading a workshop with a small team

I’m a product designer in Montréal. For nine years I have worked on software that people use because they have to, not because they want to: a trip planner, a patient form, an invoicing tool, a job sheet, a component library. The people on the other end are usually in a hurry and rarely fans of software.

My process is mostly listening and writing. I sit where the work happens: on the tram, at the front desk, in the van. Then I write the decisions down, with the options we rejected, so the team can disagree with me in week ten instead of week thirty.

Outside work I run a monthly critique night for local designers, bake bread badly and cycle all year, which in Montréal is a personality. From January 2027 I’m looking for a staff role on a team that cares about the boring parts of a product.

Hiring for a senior or staff role? Email me.

I answer within two working days. A short note about the team and the problem is plenty.
