Jagoda Gniadek

With a background in design and dev, I bridge the two by minimizing friction in cross-functional work, treating constraints as a creative input, and aligning design goals with engineering realities.
I care about solving meaningful problems and bring a practical, systems-thinking mindset to everything I do.
