03About me
From code to architecture.
I’m Dawid Bartczak. I started as a developer. Today I design and build complete systems.
My attention to detail has grown to include a broader view: the business goal and how every part of a system works together. Sometimes the best decision is to simplify a solution or leave a feature out.
I value open discussion and finding solutions together. I like understanding the perspectives of the people I work with and what matters to them. I take responsibility for delivery, from the first conversations to writing code and helping when something stops working.
