Adam Rudnicki

Lead Frontend EngineerGdańsk, Poland

I've spent a lot of years inside other people's products. A design tool where people drag layers around all day. An accounting product halfway from Ember to React. A portal for people filing disability claims.

What they share is not a stack. It's that a lot of teams, and a lot of users, depend on the interface holding up. If the person on the other side might be on a screen reader, accessibility is not a later pass. If three products need the same flow, someone has to own the shared version.

When I'm not doing that, I'm fishing, cooking, or playing guitar.
