I'm a cross-domain product designer, end to end

My background spans many interface domains, but the principles stay the same: serve the business goal, understand the user, keep development friction-free, hold a high standard. I blend rigorous UX with approachable interfaces, having worked with both dense technical data and playful, game-like products. That mix makes technical tools easier and entertainment smarter.
