Hi, my name is Przemek. (You would pronounce it like "pshemek") I live in Kraków, Poland. While I’m loving to run through the hilly landscapes, the more interesting for you is that I’m building cool things with WordPress & React.js on daily basis. My Upwork profile is relatively new but I'm in business since 13 years. What I deliver? Classic WordPress: I convert designs to dedicated themes or implement child themes while extending WordPress core by building custom plugins. Headless WordPress: I may harness core or ACF-powered WordPress as a content management system for different decoupled front-end solutions using REST API or WP-GraphQL. Gutenberg Blocks: I can develop static or dynamic blocks for the editor in React and extend the core blocks or the editor itself with new capabilities required by the project. Strapi CMS: This rapidly growing Node.js-based system helps me build easily manageable content APIs for websites and web applications. Next.js: The most advanced framework built upon React.js for API-driven front-end development allows me to create dynamic websites or apps of varying complexity. Gatsby.js: Another well-established framework admired in the headless WordPress community is perfect for me to build high-performance static websites. Whether you are curious about my work or you have an interesting project I could help you with, let's connect!

I've been working for over 5 years on Web App development. The main technologies are React.js/Vue.js/NextJS for the frontend and NodeJS for the backend. I'm experienced in working with GraphQL, Hasura, PostgreSQL, MySQL, and MongoDB. From a business perspective, I have solid knowledge in building different platforms, ERP, and CRM systems. My goal is to meet the project's goals in the most efficient way. I focus on resolving business issues not just writing code. From a processes perspective, I'm familiar with Agile, Scrum, and Kanban approaches, value CI and CD. I am a quick learner and have often learned new technologies during a short period of time to overcome obstacles or to ensure the best solution for a particular problem. I’m looking forward to working with you!
