I do Open Source. You should too!

I am Paweł and I have built my entire professional career and business on top of Open Source. This blog is one more way to share my ideas and experience, hopefully helping someone with their own adventure.

Few years into the future, Sylius is one of the most promising eCommerce platforms in the world of PHP, with over 330 code contributors and used by thousands of developers.

These days I am busy leading the project towards its stable release and managing a commercial company Lakion, which supports the community and provides training, consultation and development for brands & start-ups who want to power their business with Sylius technology.

My open source project became an exciting adventure, making developers like their job again and businesses growing thanks to its flexibility. Sylius packages have been downloaded over 2,300,000 times and power many complex applications all over the world. 


I co-founded Lakion, an IT company focused on delivering the best solutions on top of Sylius and Symfony framework. Our clients include established brands & start ups from Europe and USA.
