I don't design what I like. I design what works.

Opinions are why conversion rates get stuck. I watch real shoppers use your store, show you the exact second they give up, and hand your developer the fix.

You already know it isn't a traffic problem.

Most people running a store never get that far. Here is what it usually turns out to be instead.

Customers vanish in the checkout. Most of the reasons are fixable. Most stores never find them.

More traffic. Same revenue. Ad spend keeps climbing. Conversion hasn't moved in two years. The problem was never traffic.

You keep having the same meeting. Someone wants the hero image bigger. Someone else wants the button green. Nobody has evidence, so the loudest person wins and the number stays where it is.

You've had an audit before.

It was sixty pages, it arrived as a PDF, and nobody opened it twice. I know the format. I have been handed a few of them myself.

So this one arrives as a recording you will actually watch, and a list your developer can start on Monday. If it isn't useful, you don't pay. That has never happened, but the offer stands.

Find it. Fix it. Prove it.

Most stores skip straight to fixing. That is why the numbers never move. I start with research, design what the data asks for and prove it works before you roll it out.

01

Research

I go through your store like a real customer would. Annoyed, impatient, on a phone. Then I back every frustration up with analytics, heatmaps and session recordings.

  • Full UX audit of your store
  • Analytics and heatmaps reviewed
  • A ranked list of what costs sales

02

Design

Every finding becomes a concrete design. On brand, built from your own components, and handed over so your developer can ship it the same week.

  • Wireframes to polished screens
  • Components for your design system
  • Developer-ready handoff in Figma

03

Experiment

The new design goes head to head with the old one on live traffic. So every change is backed by numbers, not by opinions in a meeting.

  • A/B tests on real visitors
  • A clear win, loss or lesson
  • Revenue impact you can report

Six weeks from now.

You know the three things costing you the most money, in euros, in order. Your developer has Figma files instead of a Slack thread. And the next time someone says they think the button should be green, you have thirty seconds of tape that settles it.

For ANWB that was €2.8M a year. Yours will be a different number. You will know what it is.

A call tells you whether I can help. A QuickScan tells you what's wrong.

A QuickScan is a recorded teardown of your store. €995, 48 hours, straight to your inbox. You'll know within the first five minutes whether I have found your problem.

A Dutch top 50 store. 31 issues found.

Hi, I'm Philip Wallage. And I'd love to hear you pronounce that.

You'll talk to me on the sales call. I'm also the one watching the recordings and the one working in the Figma file. Everything you tell me goes straight into the design, without a handoff in between. I work solo, from Deventer, and I've been doing this for 20+ years.

The receipts

Over twenty years. ADIDAS, LEGO, KLM, Bol.com. €2.8M in annual savings for ANWB. CXL-trained.

About my background

The method

Evidence first, pixels second. I watch real shoppers use your store and let the recordings settle the arguments. No redesigns on gut feeling. Not even mine.

How I work

The model

Fixed prices, defined deliverables, no hourly meter running. You buy the outcome. If it takes me longer, that's my problem.
