#Professional WordPress Development Services

As an experienced WordPress Developer, I provide comprehensive development services tailored to your business needs. With 20+ years of expertise and 500+ completed projects, I deliver high-quality, performance-optimized WordPress solutions for businesses across Europe and globally.

#Custom WordPress Theme Development

Every business deserves a unique online presence. I create custom WordPress themes from scratch, designed specifically for your brand identity and business requirements. Unlike pre-made themes, custom themes offer:

  • Unique design that sets you apart from competitors
  • Clean, optimized code for better performance
  • Full control over every aspect of your website
  • Scalability to grow with your business
  • Better SEO foundations with semantic HTML5 and proper structure

My themes follow PSR-12 coding standards and WordPress Coding Standards (WPCS), ensuring maintainable and secure code. Each theme is fully responsive, accessible (WCAG 2.1 AA compliant), and optimized for Core Web Vitals.

#WooCommerce E-commerce Development

Professional WooCommerce development for new builds and platform migrations: from Shopify, BigCommerce, PrestaShop, or legacy carts. I build scalable e-commerce on WordPress with the integrations and perf budget production stores actually need. Services include:

  • Custom WooCommerce themes designed for conversion
  • Payment gateway integration (Stripe, PayPal, Mollie, Klarna)
  • Shipping and logistics integration (DHL, UPS, FedEx, local carriers)
  • Inventory management systems
  • Multi-currency and multilingual stores
  • B2B pricing tiers and wholesale features
  • Booking and appointment systems

#WordPress Plugin Development

Need specific functionality? I develop custom WordPress plugins tailored to your unique business processes. From simple contact forms to complex enterprise integrations, custom plugins provide:

  • Tailored functionality matching your exact requirements
  • No dependencies on third-party plugins
  • Regular updates and maintenance
  • Source code ownership
  • Security by design

#Performance Optimization

Website speed directly impacts user experience and search rankings. My performance optimization services ensure your WordPress site achieves 90+ Core Web Vitals scores:

  • Core Web Vitals optimization (LCP, FID, CLS)
  • Server-side caching and CDN implementation
  • Image optimization and lazy loading
  • Database optimization
  • Code minification and concatenation
  • PHP and database query optimization

#WordPress Security & Hardening

Protect your investment with enterprise-grade security. I implement comprehensive security measures:

  • Security audit and vulnerability assessment
  • Firewall configuration and monitoring
  • Malware protection and removal
  • Two-factor authentication implementation
  • SSL/TLS certificate management
  • Regular security updates and patches
  • Backup strategy implementation

#Headless WordPress & API Integration

Modern web architectures require flexibility. I build headless WordPress solutions using REST API or GraphQL:

  • Decoupled frontends (React, Vue, Next.js)
  • Mobile app backends
  • Third-party integrations (CRM, ERP, marketing automation)
  • Custom API endpoints
  • Webhook implementations

#A Polish WordPress developer compared to the alternatives

A foreign client comparing Polish, Romanian, Czech, Indian, Ukrainian, German, and UK WordPress developers in 2026 will not find a simple “Poland is cheaper, Poland is better” answer. The honest version is more useful.

Cost-wise, Poland is no longer the bargain it was a decade ago. Senior WordPress contractors in Warsaw, Wrocław, Tricity, Kraków, and Poznań run at 70-110 EUR/h or 130-350 PLN/h depending on stack and engagement model. That is broadly the same band as senior contractors in Bucharest, Prague, and Sofia. Where the gap appears is against UK and DACH markets: you pay 30-50% less for comparable code quality, with no compromise on tooling, Git workflow, or testing standards.

What actually differentiates Poland for a WordPress engagement specifically:

  • A deep WordPress and WooCommerce talent pool. Poland hosts WordCamp Europe events, has an active local WordCamp scene, and several WooCommerce-certified shops. WordPress is not a niche side stack here, it is a primary line of business for a meaningful slice of the freelance and small-agency market. That density does not exist at the same scale in Romania, Bulgaria, or the Czech Republic.
  • EU jurisdiction and B2B contracting that actually works. Polish developers invoice through SP. Z O.O. or one-person business (JDG) under standard EU intra-community VAT rules. For a US client, that means no W-8BEN paperwork drama, GDPR compliance is the default rather than an add-on, and disputes fall under EU law that any Western corporate counsel already knows how to read.
  • English proficiency at near-native level among seniors. Poland ranks consistently in the top tier of EF EPI for non-native English. In practice, that means async Slack threads, code review comments, and architecture documents in English without translation friction. This is the single biggest practical advantage over India: not the time zone, not the price, but the reading and writing level of the people you actually exchange messages with.
  • Time zone overlap with both EU and US East Coast. CET gives a full overlap with EU business hours and a 3-5 hour overlap with US East Coast mornings. A Polish senior on a New York account can take a 2pm ET stand-up at 8pm CET without it being unsustainable. That same overlap is much harder to schedule from Bangalore or Manila.
  • Smaller-shop ownership culture. A Polish senior on a typical 70-110 EUR/h engagement is usually the person who writes the code, runs the deploy, and answers the support email. The full-agency layer with project managers, account managers, and sales reps exists, but it is not the default for mid-size WordPress work. For a foreign client used to UK or DACH agencies, this means fewer handoffs and faster technical decisions.

What to be aware of:

  • EU labor regulations, holiday calendar, and bookkeeping. Poland has stronger employee protections than non-EU options, and the religious holiday calendar (Easter, Corpus Christi, All Saints, multiple Christmas-period days) takes more working days off the year than the UK or US calendar. For B2B contracts this matters less than for full-time hires, but it is worth planning around for tight launch windows. Polish-only bookkeeping and ZUS filing requirements also nudge most senior developers toward B2B contracting rather than employment, so the standard arrangement is contractor-to-contractor rather than employer-to-employee.
  • Rates have converged with the rest of CEE. If pure rate is the only criterion, Romania and Bulgaria are on par. Poland wins when you weight English fluency, WordPress ecosystem depth, and EU contracting maturity together. It rarely wins on price alone.

A useful frame: hire a Polish senior when you want Western European delivery quality at CEE rates, with English communication that does not require a buffer, and EU jurisdiction your lawyers already understand. Hire someone in DACH or the UK when on-site presence in those markets is non-negotiable. Hire in Romania, Bulgaria, or Ukraine when WordPress-specific depth is less important than raw cost.
