Checkout & conversion
Fewer steps, clearer errors, faster payment methods. Cart and checkout rebuilt or stabilised so mobile buyers finish the order.
- Cart & checkout UX and logic
- Gateways, wallets, local methods
- Upsells that don’t tank performance
Performance, checkout, custom development, ERP/PIM integrations and AI automation for established WooCommerce stores. Senior engineering focused on the places where a store actually makes or loses money.
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.
Large catalogues crawl. Product and category pages take seconds to load, and shoppers leave before they ever reach the cart.
Every extra step, slow field or avoidable error at checkout costs conversions on the one page where it hurts most.
Thousands of products, variations and filters bring the store to its knees; search and navigation turn slow and unreliable.
Poor LCP, INP or CLS drag rankings and hurt conversion — and "install a cache plugin" hasn't fixed it.
Prices, stock and orders drift between WooCommerce, your ERP or PIM and marketing feeds, and someone reconciles it by hand.
Twenty plugins hold the store together; every update risks checkout, and nobody wants to be the one to touch it.
Focused WooCommerce work — not generic WordPress. Checkout, performance, catalogue architecture, integrations and AI that touches real product ops.
Fewer steps, clearer errors, faster payment methods. Cart and checkout rebuilt or stabilised so mobile buyers finish the order.
Product and category pages that pass on real devices. Caching, image pipelines, script diet and query work measured on live URLs.
Variable products, attributes, faceted search and imports designed for inventories that break “default” WooCommerce.
Reliable renewals, dunning and account areas. Subscription logic that survives plugin updates and payment retries.
Stock, price and content in sync. Custom APIs, scheduled jobs and feed exports without spreadsheet archaeology.
Agents that draft descriptions, fill attributes and flag gaps — plugged into your catalogue workflow, always with human review.
Pick a lane. You get a fixed scope and a number before any build starts — not a vague “we’ll see”.
Diagnose and fix the templates that hurt conversion: product, category, cart. Lab + field data, before/after.
Cart and checkout stabilised or rebuilt for mobile: fewer fields, clearer errors, modern payment methods.
Reserved hours for features, campaigns, plugin debt and the steady stream of store tickets.
Anonymised outcomes from WooCommerce work. Full detail under NDA when it helps a decision.
Payment retries, address validation and a lighter mobile checkout cut abandonment without touching the brand theme.
Faceted navigation and query strategy rewritten so category pages stayed interactive during campaigns.

“Our WooCommerce store handles ten times the traffic it used to. The performance work paid for itself in a quarter.”

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.
Speed and UX changes are judged by conversion and stability, not by a Lighthouse screenshot alone.
Staging, rollbacks, and changes that survive the next sale. No “works on my machine” deploys into Black Friday.
You get an estimate and a plan before build starts. Scope drift is flagged early, not on the invoice.
Readable code, short notes, and no mystery plugins. You should not need me forever to keep the store healthy.
Product content and ops automation when it saves hours — not chat widgets for the sake of a slide.
Existing theme, builders, ERP and agencies welcome. I adapt to your repo and 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.
For agenciesPatch stacks grow. Revenue needs a stable checkout, fast product pages and data that stays in sync.
Quick on day one. Fragile on day ninety.
Fewer moving parts, clearer ownership.
Starting prices. Final number depends on catalogue size, integrations and how much is broken vs greenfield.
A single, contained problem
A broken gateway, a filter that times out, a cart total that lies — fixed properly, with a short note on why.
A defined chunk, to a deadline
Checkout, CWV or catalogue work scoped to what moves revenue — delivered in a focused block with before/after metrics.
Reserved, ongoing time
A block of store engineering each month for campaigns, features, debt and the tickets that never stop.
Catalogue to launch
Architecture, theme/build, checkout, payments, shipping and handover — a store your ops team can actually run.
These are starting points. Final pricing depends on catalogue size, integrations, timeline and how much custom work sits on top of WooCommerce core.
URL, what hurts (speed, checkout, catalog, ERP), traffic peaks and any hard deadlines.
I profile key templates, list risks and send a scope with estimate and start date — before any paid build.
Work lands in staging first. You see progress against the agreed outcomes, not a black box of hours.
Before/after metrics on the URLs that matter, short notes, and a store your team can keep improving.
Yes. Most gains come from queries, images, caching, scripts and checkout — measured on live product and category URLs before and after. A rebuild is only recommended when the foundation is genuinely beyond saving.
Yes. Faceted search, variable products, imports and caching strategies designed for inventories that break default WooCommerce setups. Catalogue size is part of the estimate, not a surprise later.
Yes. Custom syncs, scheduled imports and API connections so stock, price and content stay consistent — without manual CSV chaos after every supplier update.
Yes. Draft generation, attribute enrichment and catalog ops agents that plug into your WooCommerce workflow, always with human review before publish.
Classic PHP themes, block themes, and common builders when they are already in place. I optimise within your stack when possible; I recommend a change only when the stack itself is the bottleneck.
You share the store URL, the problem and any constraints. I ask a few technical questions, then return a scope, estimate and start date. Numbers are based on real work, and scope changes are flagged before they hit the budget.
Yes. Delivery under your brand is available. See the agencies page for capacity models, or just say so in the contact form.
Share your URL and what hurts — speed, checkout, catalogue or integrations. I reply with whether I can help, a rough scope and when I could start.
