A developer who stays close to the product.

I am Sándor Juhász, a Budapest-based senior web developer with more than 15 years of experience across web platforms, mobile applications and open-source development.

My work ranges from long-lived business systems to focused campaign sites. I am most useful where technical decisions need to support a clear workflow, a maintainable product and a calm user experience.

Drupal has been a constant throughout my career. I have contributed patches and modules since 2011, while expanding into REST services, Flutter applications and AI-assisted product capabilities.

I also care deeply about helping small businesses and artists build and improve their online presence.
