Hello! I'm Artur, a second-generation software programmer. My passion for computers is a family legacy, ignited by my godfather and school Computer Science teacher, and then fueled by over a decade of hands-on experience across the entire spectrum of software development.
My journey is a bridge between computing eras. It began with the structured programming with Pascal, C++ and Borland VCL, where I learned the core principles of memory management and algorithms. I then built powerful desktop and early web applications for the enterprise world using Java, JSP/JSF, Eclipse RCP/RAP and SWT, and gained a critical eye for quality and process through test automation with Selenium RC and later WebDriver, Cypress and Playwright.
I was on the front lines of the web's transformation, crafting dynamic applications with its first-generation tools: AJAX, jQuery UI, ExtJS, Angular.js, and Ember.js. This deep historical context is my greatest asset. It allows me to architect modern React, Web Components and TypeScript applications with a profound understanding of the problems they solve, ensuring they are not just trendy but truly well-engineered, scalable, and built to last.
Today, I focus on creating accessible, user-centric, offline and mobile-first Progressive Web Apps (PWA) and robust frontend architectures based on modern tools like Webpack, Vite, Next.js, MobX, React-Router, Material UI, Tailwind CSS, etc.
I've been trusted to deliver solutions for industry giants like Daimler and SAP, retailers like X5 Group ans Kohl's, tech innovators like Croc, startups like TrueImpact, Lition, Tispr/Indy and chemical leaders like Sibur and Evonik.
Now, I've come full circle: I'm passing on the logic and joy of creation to the next generation by teaching my children to code in Scratch, MakeCode and Blockly.
