What do people say about me?
Marcin is a significant part of the success of the Magento/Adobe community and our work with PWA Studio and Venia. Marcin delivered our essential desktop experience for PWA in early 2021, which addressed a top customer need. He is a regular contributor in our community and continues to create content and examples for others to get started, which is highly appreciated. Beyond the work itself, Marcin is always open to feedback and serves as a model for open source contribution. We're grateful for his help and support!
Working with Marcin was a delight, and I truly hope that this was only one in many more opportunities to come in the near future. He is a talented Frontend Engineer (with strong UX and programming things understanding) and inspirational Team Leader, always willing to take on any task or help others with theirs. He is also a great communicator, collaborator, and extremely passionate about what he is doing.
