  2. 2. Using my left brain for problem solving and analysis, and my right brain for intuition and creativity, I apply tools and techniques of design to create functional and delightful products. To me, great design improves lives, brings meaning, Kristina Marrero | 305.281.9096 | and empathizes with the user. I strive to uncover unmet opportunities, frame the problem and innovate solutions to meet the needs of the user, all with the iterative design process.
