Senior WordPress developer for WooCommerce, headless, and AI-ready sites.
WPPoland is me, Mariusz Szatkowski, a senior WordPress developer working alone since 2006. I build custom WordPress, WooCommerce and headless front ends on Astro or Next.js for clients in the EU and the UK.
Twenty years in the WordPress ecosystem, direct engagement with the engineer who ships, no junior handoff. MCP server work and GEO/LLMO-ready content when AI citations matter.
Based in Gdynia, Poland, EU. Art. 28 GDPR processing agreement before I touch your data. You deal with the person who writes the code.

Start small, no WordPress knowledge required
You do not have to start with a full rebuild
First I identify what actually blocks the project: stack, performance, technical SEO, integrations, security, or architecture.
You do not need to understand WordPress to start
If you run the company or marketing, not the code, just describe the result the site should deliver. The stack, performance, and security are my job, explained in plain language.
- A site that brings in enquiries and sales, not only one that looks good
- Fast loading on mobile (Core Web Vitals), where your customers actually are
- GDPR compliance and WCAG 2.2 accessibility, so audits and tenders are calm
- Payments and delivery tuned to your market, integrated end to end
No jargon, no commitment. A conversation first, then an individual quote. Tell me what the site should do.
WooCommerce reliability care
Checkout monitoring, controlled updates, backup verification and Core Web Vitals regression checks on a monthly plan.

Not every project should go headless. I base the decision on content, team workflow, maintenance cost, and Core Web Vitals.

My name is Mariusz
Szatkowski
As an experienced WordPress developer, I have been creating multi-language, responsive websites, online stores, and mobile applications since 2006, modifying both the front-end and back-end of services for individual client needs. I program micro-animations and information structures in websites, and optimise site code for SEO. As a WordPress programmer, I accelerate website loading times and optimise site performance according to Google Web Vitals guidelines. I patch software holes, secure, and repair websites after breaches. Since 1996, I have been creating websites and software for online campaigns, and since 2006, I have been migrating and customising client sites to WordPress. I also co-organise WordUp and WordCamp WordPress meetups, meetings of the WordPress Tri-City community.

Indexing and structured data
A site the crawler can actually read: correct headings, schema, and hreflang for every language version.
Core Web Vitals
LCP, INP and CLS measured on your own traffic before and after, not on a lab demo.
Hardening and updates
Core and plugin updates, backups, permissions and logs, before somebody else tests them for you.
Fewer plugins
Every plugin is somebody else's code in your site. Fewer of them means fewer outages and a shorter update list.
Cost of ownership
A simple site costs less over its whole life than a cheap one that needs rescuing every few months.
How much does an hour of WordPress development cost?
An hour of senior WordPress work costs 30-80 EUR net in Europe.
A build from a finished design is the cheapest, because the scope is known on day one. Extending someone else's site costs more: before we add anything, we have to read code nobody documented. A rescue after an outage or a breach costs the most, because response time is what you pay for, often in the evening or at the weekend.
A project with a closed scope gets one fixed quote, not an hourly bill. Audits, rescues and ongoing care are billed by the hour. You get a concrete figure once we have read the brief.
See the pricing bandsFrequently asked questions
Clear answers on collaboration, process, and business outcomes.
What makes you different from other WordPress teams?
#We combine business strategy with disciplined technical delivery, which means SEO, Core Web Vitals, and scalability are planned from sprint one - not bolted on later. Each milestone has explicit quality criteria tied to measurable outcomes, so you always know what is delivered and why it matters to revenue. We work in short iterations with weekly progress demos, keeping feedback loops tight and surprises close to zero. Our team also handles structured data, accessibility, and multilingual architecture as standard scope, not optional extras. The result is a WordPress site that ranks, converts, and scales - not just a polished visual presentation.
Can we start small and scale the website in phases?
#Yes, and in most cases phased delivery is the most effective rollout model for WordPress projects. We launch a focused first version that covers core business needs, cutting time-to-market by weeks or even months. Subsequent features are prioritised using real traffic data from Google Analytics and Search Console rather than assumptions. This approach lowers financial risk because each phase delivers measurable value before the next one starts. Clients typically see organic traffic growth and lead generation from the very first release, which funds further development naturally.
What happens after I submit the contact form?
#After you submit the form, I reply on working days (CET) with focused questions to clarify scope, timeline expectations, and business goals. Next, I prepare a practical proposal that includes a technical approach, a phased timeline, and a transparent cost estimate with clearly stated assumptions. Once both sides are aligned, I define implementation milestones, sprint priorities, and measurable success criteria. The entire process from first contact to project kickoff typically takes three to seven business days. This structured onboarding ensures ownership, accountability, and next steps are transparent from day one.
How much does a typical WordPress project cost?
#Project cost depends on functional scope, integration requirements, and the level of customisation needed. A focused business website with SEO and responsive design typically starts in the low thousands, while a full WooCommerce store with payment gateways, ERP integration, and multilingual support can be significantly higher. We always provide a transparent estimate broken down by phase, so you can control spend at every stage. Payments are tied to concrete deliverables rather than time elapsed, which eliminates the risk of paying for unfinished work. On request, we prepare scope variants so the project fits the available budget without sacrificing the features that drive revenue.
Do you provide ongoing maintenance and support after launch?
#Yes. The monthly care plan covers updates tested on staging first, backups kept for 30+ days in EU countries and uptime checks every 1 to 5 minutes. I work alone, so I do not promise 24/7 cover or guaranteed response times. Hours in the plan do not roll over to the next month.
How do you handle SEO and Google visibility for WordPress sites?
#We treat SEO as a core architectural decision, not an afterthought applied after launch. During the design phase, we define URL structures, heading hierarchies, Schema.org structured data, and internal linking strategy to build topical authority from day one. Core Web Vitals - specifically LCP, CLS, and INP - are optimised as part of the build because Google uses them as direct ranking signals. We also prepare the site for GEO and AEO, ensuring visibility not just in traditional Google results but also in AI-powered answers from SGE, ChatGPT, and Perplexity. After launch, we continuously monitor rankings, indexing status, and organic traffic through Google Search Console to catch and fix issues before they impact business.
