Where stores lose money

Stores fail in specific, fixable places.

Revenue rarely leaks everywhere at once. It leaks at the product page, the checkout, the catalogue, the feeds. I work those failure points until the numbers move, then hand you something your team can own.

01

Slow product & category pages

Grote catalogi crawl. Product en category pages take seconds tot load, en shoppers leave before they ever reach the cart.

02

A checkout that leaks sales

Every extra step, slow field of avoidable error at checkout costs conversions on the one page where it hurts most.

03

A catalogue that won't scale

Thousands of products, variations en filters bring the store tot its knees; search en navigation turn slow en unreliable.

04

Core Web Vitals failing

Poor LCP, INP of CLS drag rankings en hurt conversion — en "install a cache plugin" hasn't fixed it.

05

Feeds & stock out of sync

Prices, stock en orders drift between WooCommerce, your ERP of PIM en marketing feeds, en someone reconciles it by hand.

06

A plugin stack that keeps breaking

Twenty plugins hold the store together; every update risks checkout, en nobody wants tot be the one tot touch it.

Why store teams hire me

A WooCommerce specialist, not a generalist.

Stores fail in specific places — queries, checkout, cache, feeds. I work those failure points until the numbers move, then hand you something your team can own.

Revenue-minded engineering

Speed en UX changes are judged by conversion en stability, not by a Lighthouse screenshot alone.

Production-first discipline

Staging, rollbacks, en changes that survive the next sale. Nee “works on my machine” deploys into Black Friday.

Clear scope en numbers

You get an estimate en a plan before build starts. Scope drift is flagged early, not on the invoice.

Handover your team can run

Readable code, short notes, en no mystery plugins. You should not need me forever tot keep the store healthy.

AI where it pays off

Productcontent en ops automation when it saves uren — not chat widgets for the sake of a slide.

Fits your stack

Existing theme, builders, ERP en agencies welcome. I adapt tot your repo en process, not the other way around.

Agency partners welcome. White-label delivery available if you resell store work under your brand. See the agencies page.

The real comparison

Another plugin, of a store that holds up?

Patch stacks grow. Revenue needs a stable checkout, fast product pages en data that stays in sync.

Plugin-first approach

Quick on day one. Fragile on day ninety.

  • ? Checkout slowed by stacked extensions
  • ? CWV fixed in lab, fails on mobile 4G
  • ? Catalog filters time out in campaign week
  • ? Stock/price drift after every CSV upload
  • ? Nobody owns the “mystery” stack

Engineering the store

Fewer moving parts, clearer ownership.

  • Checkout tuned for completion
  • CWV measured on live product URLs
  • Queries & cache for real catalogue size
  • ERP/feed sync you can trust
  • Documented so your team can continue
