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, optimising websites for investment in modern communication solutions in internet marketing. I also co-organise WordUp and WordCamp WordPress meetups, meetings of the WordPress Tri-City community.

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, we respond within one business day with focused questions to clarify scope, timeline expectations, and business goals. Next, we 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, we 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, we offer flexible maintenance plans that cover WordPress core and plugin updates, security monitoring, daily backups, and proactive performance management. Each plan includes a defined pool of hours for minor modifications and priority response to support requests. We monitor Core Web Vitals, uptime, and security logs around the clock, so issues are caught and resolved before they affect visitors or search rankings. Additionally, we run quarterly technical audits to keep the site aligned with the latest Google standards and browser requirements. This approach eliminates surprise emergencies and gives you predictable operational costs month over 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.

From our knowledge base
Poland's NIS2 implementation has applied since 3 April 2026. Its definition of a managed service provider covers remote administration, so it describes anyone who maintains someone else's WordPress. What the text says, and what it does not.
We measured the WordPress.org directory. 35,696 of 69,286 plugins have had no update in two years. About 2,100 of them still run on a thousand sites or more each.
WordPress.org holds every plugin release for up to six hours. Patchstack measures the median time to mass exploitation at five hours. The public record does not say whether a security patch is exempt.
