I believe in giving back to the community.

People shaking hands

I've had great time working with amazing people!

Łukasz has an attention to detail and a desire to build quality, stable software, and these qualities combined make him a world class developer. 

In the years we worked together he went out of his way to learn new aspects of our technology stack, and then suggested or built improvements to the foundational aspects of our software that brought a lot of value to our customers and our developers.  

His familiarity (or ability to pick up easily) any part of the full stack is also very impressive, and it means he’s happy to come up with solutions that address the entire application (including frontend, backend, security, and UX design) rather than just a single aspect of it. 

Łukasz took it upon himself to learn about the intricacies of frontend UX design and implementation and built an entirely new, systematic approach to styling and spacing that solved many problems our frontend team had experienced for years.
