Core Expertise

Backend Development

PHP 8.x and Symfony Framework as the foundation — extending Sylius, Drupal, and Mautic platforms with custom modules, plugins, and integrations. From architecture to production.

E-commerce

Sylius custom solutions: subscription billing, digital goods with DRM, multi-store setups, and highly scalable platform architecture.

Technical Leadership

Architecture decisions, code quality tooling (PHPStan, PHP CS Fixer, Rector), automated testing (PHPUnit, Behat), CI/CD pipelines, and leading teams in an Agile workflow.

I'm a full stack developer and Tech Lead based in Toruń, Poland. Over the past 20 years I've built everything from small business websites to large-scale e-commerce platforms and marketing automation systems.

I currently lead backend development at Droptica, where I work with Symfony, Sylius, Drupal, and Mautic on projects for clients across Europe. I care about clean architecture, maintainable code, and building systems that actually work in production.

I hold a BSc in Computer Science and an MSc in Mathematics from Nicolaus Copernicus University in Toruń. I'm a fan of open source — I contribute to the PHP ecosystem and maintain ddev-sylius, a DDEV add-on for spinning up Sylius in minutes.

Outside of work: GNU/Linux, homelab tinkering, and the occasional deep dive into something that has nothing to do with my day job.
