I design tools teams use all day.#

Eight years in product, now leading design at Cobrali. I like systems, beautiful spreadsheets and taking clicks out of the way of people at work.

Selected work#

Three projects, from a design system to a billing dashboard. Each moved a number the team looked at every week.

Cobrali, the billing dashboard

Cobrali · Billing that explains itself#

2024 · design lead

I redesigned the billing dashboard of 30,000 small businesses. Support calls about "why didn't my customer pay" halved in three months.

Visitaê, the viewing calendar

Writing#

Spreadsheets are interfaces#

Why I start every dashboard in a spreadsheet, and what it teaches that Figma hides.

The button nobody clicked#

An A/B test we lost, and what we learned about trust.

Tokens without pain#

How seven countries used one system without becoming seven systems.

Shall we talk?#

I take one consulting project a quarter. The next one starts in January.

The next consulting slot opens in
