# WordPress & WooCommerce

WordPress has been my main craft since 2008. I build company sites and WooCommerce shops, write custom plugins, and take over messy builds that need a steadier hand. I also run my own WordPress products, so I know the platform as a product owner - not only as a hired coder.

How I work with you

You want the site to support sales, bookings, or content without drama. I listen for how your business actually works, then build or fix the right layer - theme, plugin, WooCommerce hook, or integration - and explain options without drowning you in jargon. That mix of technical depth and clear conversation is what years of client work teaches.

## Who it's for

Businesses that need custom WordPress or WooCommerce work from someone who ships and maintains real products - not a one-off theme tweak with no ownership afterward.

## Problems I solve

-   →Custom functionality off-the-shelf plugins cannot deliver
-   →WooCommerce stores that need development, fixes, or cleanup
-   →Unreliable sites cobbled together over years of quick fixes
-   →Need for a developer who understands theme, plugins, and hosting together
-   →Checkout, membership, or booking flows that do not match the business
-   →Fear that the next update will break something critical

## What you get

-   ✓Custom WordPress and WooCommerce development
-   ✓Custom plugins and third-party integrations
-   ✓Code review, cleanup, and stability work
-   ✓Staging-tested changes that respect updates
-   ✓Documentation and optional ongoing maintenance

## What clients usually need from WordPress

Sometimes it is a new shop. Sometimes it is "our checkout is weird," "this plugin fights that plugin," or "we need a feature nobody has packaged well." Underneath is the same ask: a site that matches how the business sells and operates.

I have worked with clients in pharmaceuticals, real estate, restaurants, memberships, retail, car rental, and more. The industries differ; the need for careful WordPress craft does not.

## Common WooCommerce problems I fix

Slow product and category pages, flaky cart fragments, checkout that breaks after a plugin update, payment gateways that only fail on mobile, and shops where every “quick fix” stacked more plugins.

I stabilize first (staging, backups, reproduce the failure), then fix the right layer — theme, custom plugin, or hosting/cache rules — so sales keep working. For pure speed work see [PageSpeed](/services/pagespeed-performance/); for a site that has outgrown endless patches see [website rebuilds](/services/website-rebuilds/).

## Built by someone who also ships products

Running plugins used by thousands of sites changes how you write client code. You learn to respect updates, avoid brittle hacks, and document decisions. That is the standard I bring to custom work and WooCommerce projects.

If the site is compromised or brittle on security, see [security & cleanup](/services/security-cleanup/) or the [hack cleanup orientation](/wordpress-hack-cleanup/).

## Technical work, normal-person conversation

I am comfortable deep in hooks, queries, and deployment - and equally comfortable saying: "Here are two options, what each costs in risk, and what I recommend." You should never need to decode the project to make a decision.

## How I work

1.  1
    
    ### Understand the business flow
    
    Checkout, bookings, memberships, forms, integrations - I map how the site should work for your team and customers before writing code.
    
2.  2
    
    ### Build or fix the right layer
    
    Custom plugin, theme adjustments, WooCommerce hooks, or API integrations - minimal code that fits WordPress conventions and survives updates.
    
3.  3
    
    ### Test on staging
    
    Real scenarios: purchase flows, admin tasks, email triggers, and mobile layouts - not just "it looks fine on my laptop."
    
4.  4
    
    ### Hand over cleanly
    
    Documentation, deployment notes, and optional maintenance so you are not stuck when something needs changing later.

## Common questions

Do you take over messy existing WordPress sites?+

Yes, often. I audit what is there, stabilize the urgent issues, and then improve or rebuild parts as needed - without pretending a pile of plugins is fine.

My WooCommerce checkout is broken or slow — can you help?+

Yes. I reproduce on staging, check plugin/theme conflicts, cache exclusions for cart and checkout, payment gateway scripts, and Core Web Vitals on product templates. Fixes are verified against real purchase flows.

Can you build custom WooCommerce features?+

Yes - custom checkout fields, pricing rules, integrations with ERP or CRM, subscription logic, and more. I prefer lean custom code over stacking ten plugins.

Will updates break your custom work?+

I follow WordPress coding standards and use hooks/filters properly so updates are less painful. No guarantees in WordPress, but good architecture helps a lot.

Do you work with page builders?+

I can, but I will be honest if a page builder is part of the performance or maintenance problem. Sometimes the right fix is less builder, more structure.

Can you explain technical choices without jargon?+

Yes. You get recommendations framed around risk, cost, and business outcome. Deep detail is available when your team wants it - it is not required to move forward.

Do you offer ongoing care after launch?+

Yes. Many clients move into a maintenance plan for updates, backups, and monitoring once the project work is stable.
