Company and brochure websites on WordPress, including large sites with many pages and language versions. I build from the design you provide, and you edit content yourself in an easy admin panel.
I design and build web solutions for businesses and agencies: from company websites and product catalogues to WooCommerce shops and custom functionality.
Are you an agency? B2B and white-label partnership

New shops and extensions of existing ones: custom theme, payments (e.g. Przelewy24), product bundles, and integrations with ERP systems and Baselinker.
Product catalogues without online sales, sites with a complex content structure and modular sections, dynamically generated price lists.
Custom WordPress functionality, dashboards and web applications in Laravel or Symfony, and further development of existing projects.
Updates, backups, fixes and new features after launch, as a separate paid service.

I am a PHP developer. I specialise in WordPress on the Bedrock architecture, and for more complex systems I work with Laravel, Symfony and Vue.
I keep the code in a Git repository. I take responsibility for the project from requirements analysis to launch, and you work with one direct technical partner throughout. I use AI tools where they genuinely save time, while keeping full control over code quality.

WordPress works well for company sites, landing pages and shops where your team edits content. I choose Laravel or Symfony when a project needs its own business logic, a dashboard or an API. I will recommend the best option once I understand your goal.
