The screen most people see on day one is the one we design last. I've started with it on every project for two years, and it keeps changing the product.
Mara · dragging[03] ABOUT
I start where the problem happens: on the reception desk, in the pay run, at the trailhead. Then I design the fewest decisions that get someone from stuck to done, and I stay until it ships.
Before going independent I designed at Fietsbank and Harbour Labs. Today I lead design at Orrin and take one outside project at a time.

Collected from delivery calls and inbox threads. Ask me for an intro.
Start a project →Ayu Lestari
Owner, wellness store
“Every sale update broke our old theme. Ilmantara rebuilt it clean, and our checkout hasn't glitched once since. Conversion went from 0.8% to 1.9% in two months.”
Misa K.
Independent illustrator
“My old commission form got maybe three requests a month. The new page with the live avatar preview gets that in a week, and half the messages mention the demo.”
Dimas Prasetyo
Founder, coffee subscription
“I gave him a messy spreadsheet of subscription rules on Monday. By Friday there was a staging link where I could pause, swap, and prorate everything myself.”
Jonas Weber
Online retailer, Berlin
“I was nervous hiring six time zones away. Then the updates started landing every morning my time, with a video walkthrough. Never felt far.”
Ratna Dewi
Boutique owner, Jakarta
“Fixed price with no surprises, the one thing every other developer got wrong. He replied on WhatsApp faster than my own team.”
Andre Wijaya
Startup founder
“Only complaint: he's usually booked, so we waited three weeks to start. Worth it. The admin panel he built saves our ops team an hour a day.”

Read the journal
The screen most people see on day one is the one we design last. I've started with it on every project for two years, and it keeps changing the product.

Four mornings on a clinic front desk taught me more than a month of interviews. People describe where it hurts, not what they need.

Components are the easy part. The hard part is agreeing what 'primary' means, and writing it down where people will find it.
[11] QUESTIONS
The questions I get in almost every first call. If yours isn't here, ask it in the form; I answer every one.
Ask something elseDigital products and websites where a real workflow needs untangling: fintech, health, commerce, travel and internal tools. I work best with teams that can ship every week.
