I’ve worked closely with Diana at JMTD Studio, and she’s an exceptional product designer. She’s especially strong at taking early-stage ideas and turning them into clear, thoughtful product direction. She thinks in systems, understands end-to-end workflows, and brings strong strategic judgment to the work, especially in emerging tech and AI. Diana stands out because she can bring clarity to complexity and help shape products in a way that’s both smart and usable. I’d recommend her to any team looking for a designer with strong product instincts and real range.

I had the pleasure of having Diana in my AI for Product Design class. Over the seven-week course, she stood out for her curiosity and willingness to experiment with new ideas. She approached AI not just as a tool, but as a creative partner; asking thoughtful questions, exploring novel use cases and design workflows, and actively contributing to class discussions. I’m confident she’ll bring that same creativity and openness to any team or project she joins.
