Mariusz Szatkowski has been developing WordPress websites since 2006. As the owner of WPPoland, he works with clients across Europe from Gdynia in Poland — fully remote, with clear written communication and on a B2B basis.
The short version of his profile: he creates multilingual, responsive websites and e-commerce stores as a WooCommerce developer, modifies both the frontend and the backend of websites to fit individual client needs, optimises website code for SEO, patches software vulnerabilities, and secures and repairs websites after hacks. He is an organiser of WordCamp Europe and WP Gdynia and a mentor for WordPress credits in the WordPress Foundation. He is a graduate of the SGH Warsaw School of Economics and is certified in Google Analytics and Shopify CRO.
Background: from 2006 to today
His start with WordPress came in 2006, in the period when the CMS was establishing itself across Europe as the foundation for business websites. What began as classic website development grew over the years into a broad engineering profile: customising themes and plugins, extending both frontend and backend, building stores on top of WooCommerce, and maintaining long-lived systems for years at a time.
That continuity is now a value in its own right. WordPress has gone through several technical generations in almost two decades — from classic PHP templates, through the block-editor era, to headless setups where a modern frontend framework such as Astro handles rendering and WordPress serves as the editorial backend. Someone who has followed that evolution from the beginning can look at any existing site and judge which route fits the architecture at hand, and which legacy parts are worth modernising.
The commercial grounding for this work comes from studying at the SGH Warsaw School of Economics, one of Poland's longest-established universities of economics. It still shapes how projects are approached: not as isolated technical tasks, but as investments with a measurable purpose.
Specialisations
- Multilingual, responsive websites: building and maintaining sites across several languages and markets, with a clean technical structure underneath.
- WooCommerce and e-commerce: developing and adapting stores, from the storefront down to payment and process logic in the backend.
- Performance and SEO: optimising code and delivery with an eye on Core Web Vitals and findability — in classic search engines as well as AI-driven answer systems (GEO, AEO).
- Security: closing known vulnerabilities in plugins and themes, hardening installations, and fully recovering websites after a successful intrusion.
- Measurement and conversion rate optimisation: certified in Google Analytics and in Conversion Rate Optimization with Shopify; decisions based on data rather than gut feeling are part of the method from day one.
How an engagement works
It starts with a short written enquiry — through the contact page, describing your situation, your goal and your timeframe. You will normally receive a written reply within one business day: not an automated acknowledgement, but an informed assessment.
That is followed by a clear scoping step: what should be built, migrated, repaired or maintained, and what scope is realistic. Only then does implementation begin — as a fixed scope for well-defined projects, or as ongoing maintenance for established systems.
The work is delivered fully remote from Gdynia, Poland. Invoicing is in EUR on a B2B basis. As an EU-based provider, European consumer law applies: there is a withdrawal form for cancelling an order, and if work is explicitly meant to begin before the end of the withdrawal period, a second consent-to-commence-performance form covers that. Both are settled transparently before a project starts, not buried in the small print.
Work in the WordPress community
A significant part of the professional identity sits outside client projects. Mariusz Szatkowski is an organiser of WordCamp Europe, the largest WordPress conference in Europe, and runs the local WP Gdynia group in the Tricity area of Poland.
Beyond that, he is a mentor for WordPress credits in the WordPress Foundation: he helps contributors get their work on core, translations or community programmes properly recorded in their WordPress.org profiles. That work keeps a direct line to the people who move the WordPress project forward every day — and to the knowledge that feeds back into client projects.
If you want to verify this perspective, the profiles on WordPress.org, LinkedIn and X are linked at the bottom of this page.
What you can expect from working together
You talk to the person who also does the work. There is no hand-off to rotating account managers and no junior pipeline whose output has to be corrected afterwards. Assessments are honest — including when the answer is that a measure will not pay off in the form you planned.
Technical decisions come with reasoning: why this architecture, why this scope, what will stay extensible later. Code changes are handed over documented, so that your own team or a follow-on agency can build on them. And the communication stays what it was at first contact: written, binding, and normally answered within one business day.
