Descripción

Hi! I’m Marina. I’m a Product Designer with 5 years of experience helping startups and B2B SaaS companies evolve. I specialize in scaling and optimizing products—using deep user research and usability testing to turn complex pain points into intuitive, high-performing interfaces. I love working at the intersection of AI and UX, building scalable design systems and making sure technical tools feel human and easy to use. Let’s build something great together!
